Prometheus¶

Introduction¶

Prometheus [1] is a point spread function (PSF) photometry package that implements many of the standard practices in Peter Stetson’s DAOPHOT package.

Description¶

Prometheus has a number of modules to perform photometry.

Prometheus can be called from python directly or the command-line script prometheus can be used.

Examples¶

Examples

prometheus¶

Here are the various input arguments for command-line script prometheus:

usage: prometheus [-h] [-p PSF] [--outfile OUTFILE] [-d OUTDIR] [-l]
                  [--fitradius FITRADIUS] [--norecenter] [-r]
                  [--verbose VERBOSE] [-t]
                  files [files ...]

Run Prometheus on an image

positional arguments:
  files                 Images FITS files or list

optional arguments:
  -h, --help            show this help message and exit
  -p PSF, --psf PSF     PSF model type
  --outfile OUTFILE     Output filename
  -d OUTDIR, --outdir OUTDIR
                        Output directory
  -l, --list            Input is a list of FITS files
  --fitradius FITRADIUS
                        Fitting radius. Default is PSF FWHM.
  --norecenter          Do not fit the x/y centroid positions when PSF fitting
  -r, --reject          Reject high RMS PSF stars.
  --verbose VERBOSE     Verbose output
  -t, --timestamp       Add timestamp to Verbose output
