STARS FROM THE GBPP LIST OF PHOTOMETRIC STANDARDS THAT ARE TO BE EXCLUDED BECAUSE OF:

(1) VARIABILITY: more than 0.1 mag variation in successive HIPPARCOS measurements
(2) MULTIPLICITY: detected by HIPPARCOS;
(3) THE ABSENCE OF PRELIMINARY HIPPARCOS INFORMATION: although the star occurs in the HIPPARCOS Input Catalogue, HIC).

In addition, the GBPP programme contained some stars that do not occur in the HIPPARCOS input catalogue and that, thus, have no HIPPARCOS data available. These are in the list below:
