There was a series of azimuth motion failures on 07dec09 and again on 31jan10. A motion failure can be caused by encoder showing that the system moved opposite to the direction requested. ... The moved the azimuth from 168 to 168+90 degrees at slew speed for the entire time. ... At each motion failure the azimuth position jumps up away from azimuth=168 (the requested position). ... All 3 failures show encoder velocity=0 while the amp velocity is non-zero prior to the failure. ...

... The amount of energy encircled by an aperture used for stellar photometry will depend on both the aperture size, and also on any variations in the PSF with field position, time, etc. ... The differences in photometric magnitude between apertures with various radii (i.e. aperture corrections), and their mean and standard deviations for the F555W filter, are presented in Table 5.5 . ... Variations in the PSF with field position will, of course, cause a position dependence in the aperture corrections. ...

... The task uvsector flags a set of visibilities based on their u-v position angle. ... If there is a glitch an a particular time, the bad data will cause a stripe pattern in the resultant image which is at right angles to the spoke. The position angle of the stripe can be used to determine the u-v plane position angle of the glitch. ... Task uvsector will flag a sector of visibility data with a given u-v position angle (or hour angle). ... You do this by specifying a long, thin region in a image. ...

... If positions are supplied in a FITS table, specified by the parameter intable , the transformed positions are written to the FITS table designated by outtable . ... The task looks for the sky-position information stored in decimal degrees in columns named RA and DEC . If uncertainties are desired, esky2det looks by preference for data of the same format in RA_ERR and DEC_ERR columns; if neither column is found, esky2det looks for a common value in arcseconds stored in a column named RADEC_ERR . ...

. Comment on J1146-3328 . The derived position here is about 20" from that of the PMN survey position (Griffith & Wright 1993). The source is only detected on the shorter baselines and is probably resolved, although some smearing may be caused by the large position offset. VLBApls home page . Last modified: 16 Oct 2000
