MYRaf
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 is in a very early
stage of development.
Features include:
- 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
