MYRaf is an open source, practical, astronomical image reduction and photometry software and interface for the Image Reduction and Analysis Facility (IRAF); a suite of tools to process and analyze astronomical images.
A variety of open source projects assist MyRaf besides IRAF. These include PyRAF, Qt, Python, and alipy.
MYRaf uses the Python programming language and the Qt framework.
Key Features
- Calibration removes spurious patterns introduced in the camera by electronic readout noise, thermal electrons, and pixel-to-pixel sensitivity variations:
- Enable zero (or “bias”) correction – zero frames establish the pattern of readout noise.
- Enable dark correction – dark frames establish the pattern and rate at which thermal electrons accumulate in the CCD chip.
- Enable flat correction – flat field images determine the pixel-to-pixel pattern caused by sensitivity variations of the pixels or shadowing (“vignetting”) by telescope optics or dust particles.
- Photometry:
- Align.
- Flip image vertically.
- Flip image horizontally.
- Rotate image.
- Variable star’s coordinates.
- Check star’s coordinates.
- Select Observatory.
- Select Method.
- Header Editor.
- Auto star finder with alipy and pySEx-tractor.
- Observatory editor.
- Cosmic Ray Cleaner.
