IRAF
IRAF is the Image Reduction and Analysis Facility, a
general purpose software system for the reduction and analysis of
astronomical data. This is primarily data taken from imaging
array detectors such as CCDs.
The main IRAF distribution includes a good selection of
programs for general image processing and graphics, plus a large number
of programs for the reduction and analysis of optical and IR astronomy
data (the "noao" packages). Other external or layered packages are
available for applications such as data acquisition or handling data
from other observatories and wavelength regimes such as the Hubble
Space Telescope (optical), EUVE (extreme ultra-violet), or ROSAT and
AXAF or Chandra (X-ray).
It has been in use since its inception in 1981 by National
Optical Astronomy Observatory (NOAO)
