build_catalog¶
Build a star catalog file from the Gaia star catalog.
This can be run if for some reason the default catalog file delivered with GIANT doesn’t meet your needs (i.e. if it
doesn’t contain high enough magnitude stars, it doesn’t blend enough stars, or similar). This script does take a while
to run so it is usually recommended to use nohup to run in the background.
Usage¶
usage: build_catalog [-h] [-f FILE] [-g GIANT_CATALOG_FILE] [-m LIMITING_MAGNITUDE] [-b BLENDING_MAGNITUDE]
[-s LIMITING_SEPARATION] [-n NUMBER_OF_STARS]
Named Arguments¶
- -f, --file
The file to save the catalog to
- -g, --giant_catalog_file
The path to the GIANT catalog file if rebuilding catalog with smaller magnitude and/or different star blending options
- -m, --limiting_magnitude
The maximum magnitude to include in the catalog
Default:
14.0- -b, --blending_magnitude
The magnitude to try and blend dimmer stars to
Default:
8.0- -s, --limiting_separation
The maximum distance allowed for stars to be blended in degrees
Default:
0.04- -n, --number_of_stars
The number of stars that can be blended to reach the blending magnitude. Set to 0 to turn off blending
Default:
0
