Stellarphot provides a Python package and accompanying Jupyter notebooks to allow you to turn reduced astronomical images of point sources (e.g. stars) into calibrated astronomical photometry, with a focus on variable star and exoplanet transit observations. Specifically:
- If you have reduced astronomical images as FITS files but haven't obtained photometry yet,
stellarphotcan perform aperture photometry on your images. - If you already have aperture photometry for a field,
stellarphotcan- calculate relative flux (like AstroImageJ), and/or
- calculate calibrated magnitudes by transforming to a catalog (e.g. APASS DR9)
- If you are working with exoplanet transit observations,
stellarphotcan turns the photometry into exoplanet transit light curves (see installation notes below).
You can install stellarphot with either pip or conda. If you are interested in stellarphot for exoplanet transit light curves, conda is recommended at the moment because of an issue with installing one of the dependencies.
-
Install with
condausingconda install -c conda-forge stellarphot reducer pip install astronbsIf you are interested in exoplanet light curve fitting, also install
batmanusingconda install -c conda-forge batman-package -
Install with
pipusingpip install stellarphot reducer astronbsor if you are interested in exoplanet light curve fitting you should instead use:
pip install stellarphot[exo_fitting] reducer astronbs
- Start Jupyterlab from the command line:
jupyter lab - Once JupyterLab opens in your web browser, open the Launcher (see Figure below)
- Click on the notebook you want (see Figure below) and follow the instructions in the notebook. Any output files will show up in the file browser
