... With the ATCA beam at 3mm being comparatively small ( ), it is possible for tracking errors to be significant. ... In additional poor tuning of the antenna drive systems can sometimes cause poor tracking, particiularly soon after a change in source. ... Tracking errors are caused by flaws in the drive servo system, whereas pointing errors are a sum of tracking errors and errors in the antenna pointing model. ... The task uvflag can be used to flag based upon rms tracking error. ...

Sloan Digital Sky Survey Telescope Technical Note 19970523 Charlie Hull and Walter Siegmund . ... A tracking error budget corresponding to the goal is given in that Technical Note. This budget was subsequently updated based on measurements in "2.5-m Telescope Drive Measurements IV: Acceptance Testing" (Sloan Digital Sky Survey Telescope Technical Note 19950608). Table 1 : Tracking error budget. ... Drive disk 2-D high freq. error . ... Az encoding error . ... Encoder capstan error . ...

... This is not important for drift observations but poses a problem for any observing mode in which the telescope is moving while taking data, since the ALFA beams then will be rotating on the sky. ... The new mode is called ' sky angle tracking ' and is available for all existing observing modes. ... The next figure shows the distance between the beams in declination as a function of hour angle when the telescope is tracking a source with Dec=+10 from rise to set with a sky angle of 19 degrees. ...

Observers should be aware that moving targets are tracked by HST with the assumption that the object is moving on a linear track with constant velocity. ... The scheduling software sets a generally appropriate limit on the duration of a linear track (which depends on the target being tracked, but not on details of the target motion at the time...
