Astronomical Data Analysis Software and Systems VII ASP Conference Series, Vol. ... Be well placed to take advantage of new astronomical software and tech­ niques The above requirements are not, of course, unique to UKIRT; and it seems that the astronomical software community in recent years has shifted from large instrument­specific programs to data reduction pipelines. ... An algorithm engine: One or more generally available packages containing suitable algorithms for data reduction . ...

IRAF/STECF 2-D spectrum point source / background decomposition package . ... The general problem is one of spectral decomposition - of separating the spectra of the point sources from the background. ... The STECF IRAF layered package "specres" provides two tasks to extract point source spectra from 2-D images (either longslit, multislit or cross-dispersed) and decompose the full background over the image. ... A Point Source Function spectrum image is required as a 2-D spectrum. ...
