goodman-photometry 1.1.0

Pipeline for reducing Goodman HTS data.

Goodman Photometry

Routines to perform automatic astrometry and photometry of Goodman imaging observations.

The codes were initially based on STDPipe (https://github.com/karpov-sv/stdpipe) and adapted for Goodman HST.

Features

• Performs automatic astrometry to add celestial WCS to FITS files
• Calculates photometric zero points using Gaia-DR2 catalog
• Includes auxiliary functions for data processing
• Provides both command-line and Python API interfaces

Installation

To install the package, run:

pip install goodman-photometry

Prerequisites

• Python 3.10+
• Required dependencies:
  • astropy
  • astroplan
  • ccdproc
  • cython
  • matplotlib
  • numpy
  • packaging
  • pandas
  • requests
  • scipy
  • statsmodels
  • astroquery
  • sip_tpv
  • setuptools

Usage

Command Line Interface

The package provides command-line scripts for processing observations:

#Process astrometry
redastrometry -i input.fits -o output.fits

# Process photometry
redphotometry -i input.fits -o output.fits

Python API

You can also use the package as a library in your Python code: from goodman_photometry import Astrometry, Photometry

Initialize astrometry processor

# The values of the parameters are set to the default values. So an empty call will work as well.
astrometry = Astrometry(
    catalog_name='gaiadr2',
    magnitude_threshold=17,
    scamp_flag=1,
    color_map='Blues_r',
    save_plots=False,
    save_scamp_plots=False,
    save_intermediary_files=False,
    debug=False
)

# Process the FITS file
astrometry('input.fits', 'output.fits')

# Initialize photometry processor, it will use the default values for the parameters.
photometry = Photometry()
photometry.process('input.fits', 'output.fits')
