CONSFIG (A0): Visual constellation figures & IAU boundaries (19911106)
FILE: consfig.a0 (89 entries)
CONTENTS: Visual constellation figures and IAU equinox 1875 boundaries (19911106)
DATASET: This file comes in HyperSky dataset A-0.4, version 19911106 (part of the original basic dataset supplied with HyperSky). Availability on HyperSky CD-ROM: Vol. 1 (1993)
DESCRIPTION: This datafile contains the official IAU (International Astronomical Union) equinox 1875 boundaries for the constellations as given in "Delimitation Scientifique des Constellations", by Eugene Delporte 1930. Although there are 88 constellations, there are 89 areas defined in the datafile since once constellation, Serpens, appears in two separate parts of the sky, known as Serpens Cauda (the Serpent's head) and Serpens Caput (the Serpent's tail).
DATA: By its nature, the datafile covers the entire sky. Included in the displayed text information are the full Latin constellation name, the 3-character constellation abbreviation in parentheses, and finally the equivalent English name. The English equivalent is particularly useful for some of the obscure southern constellations, which can be unfamiliar to the majority of northern hemisphere users.
If you set a non-BLACK line color for this file lines are drawn that connect the brighter constellation stars. These figures are intended to represent popularly-recognized patterns defining the constellations. However, since there is no "official" figure set equivalent to the IAU boundary set, the drawn figures may not agree with your own experience or preferences. The figures will appear in your chosen color when you request datafile information (using ENTER or the right mouse button) or draw the boundaries (using the 'b' command).
