CONTENTS: Burnham's Celestial Handbook - noted objects
DATASET: These files come in HyperSky dataset M-1Availability on HyperSky CD-ROM:
Vol. 1 (1993), version 19921101
Vol. 2 (1995), version 19940530
DESCRIPTION: This datafile is a cross-reference to objects in the popular Burnham's Celestial Handbook which were notable enough to receive more than just a table entry in the handbook constellation tables. Included in the HyperSky files are objects about which there are extended notes in Burnham's constellation sections, for which there are diagrams or photographs, or which appear in various special handbook tables.
Although Burnham's handbook is organized by constellation, no constellation identifications are included in this file since it is assumed the user will also use the HyperSky constellation boundary file CONSTEL.A0 to identify the constellation in which an object is located.
DATA:
MAG: visual magnitude as provided in the handbook. For a very few objects for which no handbook magnitude was provided, an alternate magnitude from other available sources has been used.
TYPE: object type generally according to the same 2-character code used in HED, the HyperSky data editor. See the paragraph "OBJECT DATAFILE CLASS TYPES" in the user's manual DATAFILES section for a description of these codes.
IDENTIFICATION: the object identification as provided in the handbook.
COMMENTS: Comments include the handbook page number where is the object is discussed, plus brief additional remarks noting the object's significance.
NOTEFILE: Each notefile entry includes a brief summary of interesting object highlights, followed where appropriate by additional handbook page references to photos, diagrams and charts concerning the object. The user should be aware that most notefile information is in cursory or truncated form. For example, a distance listed in the notefile may be only one of several possible values discussed in the handbook. Likewise, a variable star period listed in the notefile as 10.5 hours might appear in the handbook as 10.51243 hours. The user should always refer to the cited handbook entries for full and accurate information.
