Compact star databases for the ASTAP program:

Star databases usability:

D80 star database for 6°>FOV>0.15°
D50 star database for 6°>FOV>0.2°
D20 star database for 6°>FOV>0.3°
D05 star database for 6°>FOV>0.6°
V50 as D50 but for photometry.
G05 star database for 20°>FOV>3°
W08 star database for 80°>FOV>20°


ASTAP for Windows users:
Download and install the D80 or D50 database installer (d80_star_database.exe or d50_star_database.exe ). If you want to save disk space the D20 or D05 instead depending on your setup field-of-view. You will need only one database. Alternatively you can continue using the older H18 or H17 database.


ASTAP for Linux users:
Download and install the D80 or D50 database package (d80_star_database.deb or d50_star_database.deb). If you want to save disk space the D20 or D05 instead depending on your setup field-of-view. You will need only one database.  The files will be placed in the ASTAP program directory /opt/astap.


ASTAP for macOS users:
Download and install the D80 or D50 database pkg file (d80_star_database.pkg or d50_star_database.pkg).  If you want to save disk space the D20 or D05 instead depending on your setup field-of-view. You will need only one database.  The files will be placed in directory /usr/local/opt/astap.

For the rare case you have more then one database installed and the selection is set on auto then the database selection will be as follows:

FOV>20° ==> if exist W08
ELSE
FOV>6° ==> if exist G05
ELSE
FOV<0.5° ==> if exist D80
ELSE
==> if exist V50, D50, D20, D20, G05


The database is sorted on star density. D80 indicates 8000 stars per square degree. D50 indicates 5000 stars per square degree. D20 indicates 2000 stars per square degree. D05 indicates 500 stars per square degree. Epoch is fixed at year 2025. The magnitude is the Gaia Bp except for V50 which contains the calculated Johnson-V magntude and Gaia Bp-Rp.

Unless manually selected, ASTAP will use in order of preference: D80, V50, D50, H18, H17, D20, D05. You can force a star database in ASTAP, tab alignment (ctrl+A). 

Hyperleda, is a very large galaxy database for deep sky annotation. Contains 4.970.062 objects. Based on extract from http://atlas.obs-hp.fr/hyperleda/  For macOS a 2.1 million object Hyperleda database is included with the star database. This will be overriden with the available update.

and in the source code

Clear skies, Han

This is an extract from HyperLEDA  database from  http://leda.univ-lyon1.fr 

HyperLEDA is a database and a collection of tools to study the physics of galaxies and cosmology. The project, started in 1983, is currently maintained by a collaboration between Observatoire de Lyon (France) and the Special Astrophysical Observatory (Russia).

The principle behind HyperLEDA is to collect measurements published in literature and modern surveys, and to combine them into a unique homogeneous description of the astronomical objects. This enables the researcher to compare objects located at very different distances. This approach is a continuation of the famous series of Bright Galaxy Catalogues (RC1, RC2, RC3) by de Vaucouleurs and co-workers. The result of the homogenization is the Leda catalogue.

HyperLeda is not only used by researchers, but also by sky lovers or amateur astronomers interested to learn more about galaxies, by students, and by professors. HyperLeda is developed in the frame of the Virtual Observatory, an initiative intended to facilitate the exchange and usage of the data at the global scale. All the data and the software is publicly available in open-source for non-commercial purposes.
