Overview

Set of modules developed in Astronomical Institute of Wroclaw University. Contains wrappers for daophot package, star lists manipulation as pandas DataFrames with export/import to daophot and ds9 formats, genetic algorithm for searchin for optimal PSF stars and other.

Instalation

$ pip install astwro

Note

You must have modern DAOPHOT suite installed to use pydaophot module (no no no IRAF’s daophot).

Modules

Package contains following modules:

• pydaophot - wrapper for Peter Stetson’s DAOPHOT photometry suite:

d = astwro.pydaophot.Daophot(image='i.fits')
res = d.PHotometry(IS=35, OS=50, apertures=[8])

• starlist - provides pandas objects for stars list, with import/export do daophot and ds9 formats.

s = res.photometry_starlist.sort_values('mag')
psf = astwro.starlist.read_dao_file('i.lst')
astwro.starlist.write_ds9_regions('i.reg', color='blue', indexes=[psf.index], colors=['red']) # PSF stars red

• utils - some helpers for scripts.

dir = astwro.utils.tempdir('i.lst')
f = open(os.path.join(dir.path,'notimportant.txt'), 'w')

• tools - command line (callable form python also) tools including gapick for finding optimal PSF-stars set using generic algorithm.

$ gapick.py -od results -c i.coo i.fits
