This catalogue contains photometric parameters (absolute magnitudes and slopes) and their error estimates for 421,496 asteroids. The phase curves have been obtained from the re-calibrated Minor Planet Center photometry. The re-calibrated photometric data have been fitted with three phase functions: (H,G), (H,G1,G2), and (H,G12).

For the description of the phase functions please see Muinonen et al. (2010). For the description of the calibration and fitting procedures please see Oszkiewicz et al. (2011) . Other related articles are Oszkiewicz et al. (2012) and Bowell et al. (2012).

If you are planing to use this catalogue please refer to Oszkiewicz et al. (2011) and Muinonen et al. (2010). For the post-processing of the catalogue: please note that the re-callibrated data are of low precision (roughly around 0.1 mag) and accuracy (roughly around 0.2-0.3 mag) which is reflected in the photometric parameters accuracy. If you have any questions concerning the database usage please contact D. Oszkiewicz.

The Catalog Format

The catalog is distributed as zipped ASCII file with one record (line) per object. Values are separated with space and missing values coded with -999 999. Records are ordered by the designation number , and each record contains:

† A temporary designation code is used for asteroids without a designation number. The two first numbers of the temporary designation are left out, and the rest is concatenated together, e.g., temporary designation code for object 2000 AC 229 is 00AC229.
