astroimred
Read FITS files, combine exposures, and measure sources.
Start with the FITS quickstart, then follow the reduction learning path. The examples start with synthetic images before introducing observation files.
astroimred connects FITS file management, image reduction, and photometry through Astropy CCDData. Array combination uses imcombiners; pixel-aperture geometry uses astroapers.
| Your task | Start here |
|---|---|
| Read and inspect FITS files | Quickstart |
| Apply bias, dark, and flat masters | Calibration |
| Combine calibrated exposures | Image combination |
| Process FITS files from a terminal | Command-line tools |
| Find arguments and return values | API reference |
Continue to aperture photometry when your images are ready for source measurements.
Install
Use Python 3.11 or newer. Install the full extra for all examples on this site:
uv pip install "astroimred[full]"import astroimred as airThe API reference uses canonical module paths. Convenience imports such as air.load_ccd and air.fits_summary remain useful for short scripts.
