Comparing the summed map with the maps from the individual energy ranges, the one which produced the smallest error box was chosen to represent the source position, as long as was greater than 4, a level chosen to reflect a reasonable degree of confidence in the detection. ...

... The Figure shows the parallactic angle in relation to the source position at (RA,DEC), the zenith of the telescope at (LST,AoLatitude), the hour Angle HA, and the azimuth direction AZ (in the picture the source has already transitted). ... Now suppose that a second feed was placed 1 beam width away from the central horn parallel to the azimuth arm. ... Figure 1. shows the parallactic angle rate versus azimuth angle for declinations 8 through 28 (spaced 1 degree steps from Arecibo's latitude). ...

... From the chain visibility point of view, it is very recommended to look at the Javascript movies , especially if the frame rate can be not regulated in your MPEG player. ...

Comment on J2246-1206 . In contrast to the jet pointing to the NE in our image, the 5 GHz VLBI image of Shen et al. (1998) shows no indication of extended emission above the 20 mJy/beam level. Hong et al. (1999) find a jet component to the SE and identify that with a "superluminal" component possibly ejected in 1992. A 15 GHz image from the USNO database, taken nearly at the same epoch as the image of Hong et al. (1999) does not show any component at this position angle. ...
