. Comment on J0604-3155 . No detection: the source has a relatively steep spectrum, alpha=-0.62, in the frequency range from 80 MHz to 8 GHz and the position is probably okay. Hence, the source is probably resolved. VLBApls home page . Last modified: 16 Oct 2000

... In the spectrometry of point sources, the advantage of obtaining long slit spectra over using single aperture spectra is that it provides a simultaneous spectrum of the background on both sides of the point source. ... 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. ...
