... 1Becker A catalog of 53522 4.85 GHz sources between 0 and 75^o declination has been generated from observation taken with the NRAO Green Bank 300 foot (91m) telescope. The flux limit of the catalog is dependent on confidence radius of ~50". Spectral indices have been calculated for 29051 sources which have counterpart in the Texas 365 MHz northern sky survey. ... The rms noise in the images varied from 5 to 8 mJy. The images has an angular resolution of ~3.5'. ...

... Alfa_ang is a GUI for the rotang routine. The purpose of this routine is to calculate the optimum rotation angle for ALFA given the RA and Dec of a source and the date and time of the observation. The routine also returns the azimuth and zenith angle of the telescope at the requested time, thus it can be used to find the correct rotation angle and azimuth for the Fixed Azimuth Drift Scan observing mode used by the AGES drift precursor observation. ... To run alfa_ang at Arecibo: . ...
