... 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. ...
