ASTSCRIPT-PSF-SELECT-STARS(1) User Commands ASTSCRIPT-PSF-SELECT-STARS(1) NAME astscript-psf-select-stars - Select good stars for constructing the PSF SYNOPSIS astscript-psf-select-stars [OPTIONS] image.fits DESCRIPTION Build a catalogue of "good stars" that will be considered for con- structing an extended and non parametric PSF. Here, "good stars" means that they don't have close objects that affect it sourrondings and con- sequently they are not contaminated. The script will construct a cata- log of stars from reference datasets (Gaia) if the user does not pro- vide another one. In addition to this, other parameters like the axis ratio are considered to filter the sample and select only proper stars. astscript-psf-select-stars options: Input: -h, --hdu=STR/INT HDU/Extension name of number of the input file. -S, --segmented=STR Segmentation file obtained by Segment (astsegment). -D, --dataset=STR Query dataset ("gaia --dataset=edr3", etc.). -r, --racolumn=STR Right Ascension (R.A.) column name. -d, --deccolumn=STR Declination (Dec) column name. -f, --field=STR Magnitude column name ("phot_rp_mean_mag", for Gaia). -p, --parallaxanderrorcolumn=STR,STR The name of the parallax column. -m, --magnituderange=FLT,FLT The range of magnitude. -Q, --minaxisratio=FLT Minimum axis ratio to be accepted (default to 0.9). -M, --mindistdeg=FLT Minimum distance to more bright neighbour stars. to be ac- cepted, in degrees. -c, --catalog=STR Catalog of stars containing: ra, dec, magnitude, parrallax, par- rallax_error. -a, --matchaperturedeg=FLT Aperture, in pixels, to match catalogue ra and dec coordinates with clumps' ra and dec. -F, --faintmagdiff The difference from the faintest star which the user will be de- termined the faintest star in '--magnituderange' option. -b, --brightmag The limit for selecting wider range of bright stars. Output: -o, --output Output table with the object coordinates. -t, --tmpdir Directory to keep temporary files. -k, --keeptmp Keep temporal/auxiliar files. Operating mode: -h, --help Print this help. --cite BibTeX citation for this program. -q, --quiet Don't print any extra information in stdout. -V, --version Print program version. Mandatory or optional arguments to long options are also mandatory or optional for any corresponfing short options.
