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 searching for optimal PSF stars and other.

Installation

.. code:: bash

$ pip install astwro

You should setup paths to executables (e.g. your daophot). See documentation <https://astwro.readthedocs.io/en/latest/installation.html#astwro-cfg-configuration-file>_.

.. note:: You must have modern DAOPHOT suite installed to use pydaophot submodule (not IRAF's daophot).

Modules

Package contains following modules:

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

.. code:: python

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.

.. code:: python

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.

.. code:: python

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.

.. code:: bash

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