APASS (DR9) Catalogue

The AAVSO Photometric All-Sky Survey (APASS) is a catalogue of 61,176,401 stars covering the sky from -90 to +90 degrees in declination, down to magnitude +16, and containing many dimmer stars. The emphasis is on accurate photometric magnitude data. More information can be found here.

The AstroPlanner version of this catalogue consists of three files: North (Declination +20° to +90°), Central (Declination -20° to +20°), and South (Declination -90° to -20°), a total of 5GB in size, and contains the RA/Dec and V-Magnitude for each star. The Notes field contains data for B, B-V, i', r' and g' magnitudes (where available). The included information is unchanged from the original catalogue.

Notes

1. The catalogue is supplied on a Flash Drive, in compressed form. It is not usable directly from the Flash Drive, and requires 5GB of hard disk space for (a complete) installation.
2. In theory, the catalogue (or parts thereof) could be burned onto a DVD-ROM and used directly from there, but access would be extremely slow.
3. The catalogue is in a format only understandable by AstroPlanner, and cannot be used by other applications.
