Field 53: CPD number

The format is ZZ NNNNN


Reliability tests were performed to check the coherence between the zones of the DM (BD, CD, and CPD) numbers and the declination at the epoch of the catalogue (1855 for BD, 1875 for CD and CPD), and also to check that the numbers increased with increasing right ascension at the epoch of the catalogue. Resulting corrections (from typing errors in the numbers or in the coordinates, originating from the source catalogue themselves or from an intermediate transcription, or confusion between the CD and CPD identifiers) have been included in the Hipparcos Input Catalogue.
