The hipparcos catalogue
WebAn amplitude of 0.05 magnitudes about an apparent magnitude of 6.82 has been derived from Hipparcos satellite photometry. The same photometry found a possible period of 0.82 d but this was very uncertain and no variability type could be determined. It is listed in the General Catalogue of Variable Stars as a possible slow irregular variable. WebWe have calculated improved photonic passbands for the , Hipparcos and Tycho , , standard systems using the extensive spectrophotometric libraries of NGSL and MILES. Using the passband, we adjusted the absolute flux …

Stars were observed as the satellite rotated, by a sensitive region of the image dissector tube detector. This pre-defined star list formed the Hipparcos Input Catalogue (HIC): each star in the final Hipparcos Catalogue was contained in the Input Catalogue.
