Add Barnard catalogue of dark nebulae, and (optionally) allow proportional DSO symbols.

This branch adds the Barnard catalogue of dark nebulae, and allows for proportional DSO symbols.

[Alexander Wolf (alexwolf)]

Georg, why you don't use decimal values for coordinates?

review: Needs Information

[gzotti (georg-zotti)]

Did I overlook some guidelines again?

I just took the list from DVAA as-is, including all their data, and did the data processing during read-in of the file. In case they (DVAA) change something, the list can be updated most easily.

[Alexander Wolf (alexwolf)]

No, it's not in guide :) Just for note - default DSO catalog has decimal values of coordinates.

+9 	4 	18 	  	+55 3 	  	? 	Dark, irregular vacancy. This is the middle of a great vacancy extending east and west, the continuous part of which is 2.5 degrees long and about .5 degree wide. It really extends in a more or less broken form for about 6 degrees. There is a wide region extending south of it for a couple of degrees, nearly to the star BD +53 750 (magnitude 5.0) whose position is 4h6m58s, N 53 18' (1875.0). To the east it breaks up into more or less separate spots, somewhat resembling those at the east end of the great lane from Rho Ophiuchi, but unlike that lane it does not originate in a larger vacant space or a nebula. Its borders are not so definite as the Rho Ophiuchi lane. It is approximately bounded by the coordinates 3h58m, N54.7 and 4h20m, N54.8. The individual positions of some of the spots are given in the catalogue. 	28 	Camelopardalis

+15 	4 	31 	56 	+46 37 	13 	5 	Elliptical; diameter 15' x 10' slightly NW and SE. One of the finest examples of a dark object seen against the ordinary sky and away from the Milky Way. The background on which the stars shine is uniform over the entire plate. The object is in a region somewhat larger than itself, where there are relatively few stars, and is black by contrast with the sky alone. It clearly shows the presence of a feeble uniform luminosity in space which, from the appearance of similar objects in widely different parts of the sky, leads to the belief that this feeble illumination of distant space is universal. If this object were seen against the star clouds of the Milky Way it would appear strikingly black. 	42 	Perseus

+20 	4 	37 	4 	+50 58 	60 	2 	In S part of larger, relatively vacant area; this is the dark object mentioned by Espin in Monthly Notices, 58, 334, (1898MNRAS..58..334E). It is close north of a small group of faint stars and is 6' or 8' in diameter. In a somewhat larger vacant space (sic). It is not so definite as B 15. 	42 	Perseus

+22 	4 	38 	  	+26 3 	120 	4 	Irregular; unequally dark; extended SE and NW; this is a very large region of obscure nebulosity with several darker streaks in it trending northwest. It is partly separated from another starless region lying about 2 degrees to the west and north. Near the middle of the first of these regions is a small luminous nebula with a faint fan-shaped extension for 10' to the northeast (B 14). This is undoubtedly a brighter condensation of the great obscuring mass surrounding it. The position of this small nebula is 4h32m20s, N25 30' (1875.0). 	78 	Taurus

Apparently this nebulous border extends many degrees east in a very diffused manner. There is a narrow dark lane extending south from the semi-vacant region, running close west of BD +12 803 to a point nearly 1 degree south of BD +12 801 (mag 6.9). There is a small fan-shaped nebula close north of small star in the position 5h24m30s, +12 3.9' (1875.0). A small strip of nebulosity extends 5' southwest from this star. These two nebulae are probably the brighter parts of a large obscure nebulosity. 	96 	Orion

+37 	6 	32 		[phone] 	Irregular, semi-vacant region. This region is abruptly terminated on the S side by the nebulosity extending north from 15 Monocerotis. Its west side ends abruptly at 6h22m15s, +12 26' (1875.0). B 37, 38, and 39 are shown in Plates 28 and 29, Lick Observatory Publications, 11, 1913. 	96 	Monocerus
+38 	6 	33 	41 	+11 4 	60 	4 	Irregular vacancy. This seems to refer to a portion of B 37. 	96 	Monocerus

[phone] 	-18 58 	15 	3 	Diffused dark spot; small star in it. This spot and B 41 are connected with the great nebula about Nu Scorpii and are doubtless denser opaque masses of the nebula. There is a larger dark region belonging to this same system in B 43, from which broken dark lanes somewhat like those from Rho Ophiuchi, though less marked, run eastward for some degrees. 	147 	Scorpius
[phone] 	-19 37 	45 	3 	Diffused dark spot 	147 	Scorpius
+42 	16 	25 		-23 26 		6 	Great nebula of Mu Ophiuchi; this object is put in the list because, though not wholly dark, it is partly so, and the evident obscuration produced by it puts it in the class for which the catalogue is made. The semi-vacant region in which this, the great nebula of Rho Ophiuchi, lies is about 3.5 degrees in diameter. For references to the visual discovery and early observations of this strange region see Astronomische Nachrichten, 138, 211, 1895; Popular Astronomy 5, 227, 1897; 14, 581, 1906; Lick Observatory Publications, 11, 19, 1913 and Plate 36. 	147 	Ophiuchus

+44 	16 	40 		-24 4 		5 	Dark lane E. from Rho Ophiuchi region. This is the middle of the main part of the great vacant lane that runs east from the region of Rho Ophiuchi. It is about 32' wide and has its beginning in a vacant area in which is the star 22 Scorpii (CD -24 12695, magnitude 5.5). It runs slightly northeast to about 16h40m, -23 40' (1875.0). From this point it extends in a broken chain of dark spots to a little south of B 63. Its total length is therefore about 10 degrees. 	147 	Ophiuchus
+#44a 	16 	44 	45 	-40 20 	5 	5 	Irregular; sharpest on SE side; CD -40 10662 (mag 9.0) close N. Apparently a real dark object. 	164 	Scorpius
+45 	16 	46 	  	-21 35 	120 	5 	Rather definite; Extended NE and SW with an irregular projection SW that connects it with the Rho Ophiuchi region. This appears to be a real, dark object. 	146 	Ophiuchus

+48 	17 	1 	  	-40 41 	40 	5 	Fairly well defined; 15' W and N of CD -40 11088 (magnitude 8); seems to be a real object. 	164 	Scorpius
+49 	17 	2 	39 	-33 16 	  	3 	Small; close SE of and involving CD -33 11668 (magnitude 9.3). 	164 	Scorpius
+50 	17 	2 	54 	-34 23 	15 	6 	Large, irregular dark space; this is an irregular square, sharply defined on the east side and diffused on the west, where there are broken extensions for 30'. The star CD -34 11418 (magnitude 9.8) is near the middle. The stars CD -34 11422 (magnitude 9.8) and -34 11427 (magnitude 9.9) are on the eastern border. 	164 	Scorpius
+51 	17 	4 	44 	-22 15 	20 	6 	Definite; one of a straggling group toward the eastern end of the dark lane from Rho Ophiuchi. Two irregular, dark lanes run west from it to B 47. 	146 	Ophiuchus
+53 	17 	6 	  	-33 35 	60 	4 	Large; diffuse; extended N and S by 30'; curved toward the E at N end. 	164 	Scorpius

+56 	17 	8 	48 	-32 5 	3 	5 	Small; close E of CD -31 13609 (magnitude 9.0). This seems to be a real object. 	164 	Scorpius

+63 	17 	16 	  	-21 28 	60 	3 	Large, definite, curved figure, convex to N; the W end abrupt; 97' E and W, 19' wide 	146 	Ophiuchus
[phone] 	-18 29 		6 	Cometary; W of M 9; This object is somewhat cometary in form and has a very black core or head that sharply abuts against the thick stratum of stars; from this it spreads out into a large dark area with much dark detail, filling quite a space close southwest of M 9. It thus resembles a dark comet with a dense and well-defined head and diffused widening tail. The position of the head is 17h9m57s, -18 20.6 (1875.0). 	146 	Ophiuchus

The SE branch runs E for some distance passing close S of the star CD -23 13376 (magnitude 9.1). Its average thickness is about 2'-3'. The position in the catalogue is for the southern part of the figure, or the bottom of the S (see Astrophysical Journal, 49, (1919ApJ....49....1B), Plate III). 	146 	Ophiuchus

In Monthly Notices, 69 (1908MNRAS..69..117W), Dr. Max Wolf gives a photograph of the nebula, stating that the object was discovered by Dr. Kopff at Heidelberg on October 12, 1908. It is conspicuous on a photograph of mine made with the Willard lens at the Lick Observatory, September 24, 1895, with 5h0m exposure. It is also shown on a photograph of mine made with the Bruce telescope, July 20, 1904, with an exposure of 3h1m. By inadvertence reference to this object was omitted in Lick Observatory Publications, 11, where it is cut out by the matting in Plate 83. 	9 3 	Cepheus
