CONTENTS: Objects in the Hubble Atlas of Galaxies
DATASET: These files are part of HyperSky dataset G-3 (G3.2), version 19890329 Availability on HyperSky CD-ROM: Vol. 1 (1993)
DESCRIPTION: This short dataset displays those objects pictured in the Hubble Atlas of Galaxies (second printing, 1962). Though strictly black & white, the atlas plates are generally excellent, including many beautiful half- and full-page images. These images cover all the various morphological types of galaxies first recognized by Edwin Hubble and his contemporaries.
Although there have since been a number of larger photographic atlases of galaxies published, the Hubble atlas was the first to be made available on a wide scale to amateurs. It still has special significance since it was published by one of the pioneers of extragalactic astronomy.
The dataset is of type "m0" (miscellaneous objects) rather than type "g0" (galaxies) because of two objects noted on the atlas plates. The first is NGC 2070, otherwise known as the Tarantula Nebula or 30 Doradus, which is the largest HII region in the Large Magellanic Cloud. The second object is NGC 604, a giant HII region in the Triangulum galaxy M33.
DATA: The HyperSky datafile contains the following data from the atlas:
MAG: The apparent magnitude of each object, taken from various sources. Magnitudes were not provided in the atlas itself.
IDENTIFICATION: Usually the NGC or IC number.
COMMENTS: The comment line contains the following additional information, provided if available for each galaxy:
* Alternate identifications or common names, eg, "Virgo A" or "Sombrero".
* Very brief appearance descriptions, ie, "face-on" or "spindle".
NOTEFILE: Each object is described in a manner analagous to that below, used to describe NGC 3367:
Hubble:49:1/6:bw: type SBc(sr) with branching arms nearly forming bar ring.
The above description says that the NGC 3367 can be found on atlas plate 49, and is a black & white image covering about 1/6 of an atlas page. (Usually this implies that there are also 5 other images on that page). After this the Hubble type is given, followed by brief remarks usually extracted from the longer description provided in the atlas.
