History
Over the course of the decade of the 1920s, the IAU officially defined the borders of the constellations as lines of constant right ascension and declination (for the equator and equinox of B1875.0). This definition is used as international standard in research papers.
However, there is no single date of the definition but there are actually some very important dates:
- 1922 The international standardization of 89 Latin constellation names:
- in nominative and genitive forms and their three-letter-abbreviations.
- the defunct constellation Argo (Arg) was also included for historical reasons.
- 1925 Delporte's presentation of his definition of border lines.
- 1928 the acceptance of Delporte's suggestion.
- 1930 publication of Delporte's delineation of the constellation boundaries[1] with an accompanying celestial atlas.[2]
The origins of these constellations are diverse.
Constellation from a given position
Algorithms for determining the IAU constellation from a given celestial position were published by Roman[3] and Glaschke.[4]
