A2055: galactic mapping zoa piggyback

mar05

Intro:

    A2055 is doing galactic mapping with galfa. It is running in drift scan mode and then driven basketweaving on the meridian. At the same time, the wapps are acquiring data for a zoa search (it actually has another number but i'm not sure what..).

Drift scanning:

    The drift scanning is to make a map. They move in az,za to the start of the map and then let the telescope drift for 840 seconds. The cal diode is the fired. The telescope then moves to the start of the next strip (a strip is defined by the width of the alfa beampattern).

  • 23jun05: ra/dec (j2000) coverage of drift scans for 22/23jun05 (.ps) (.pdf). Black is 22jun05,red is 23jun05. Each line is 1 pixel of alfa. The ragged edges are because the 7 beams are not starting at the same ra. The positions computed from the az, za and the time stamp of the data. The positions are at the start of each second (they have not been interpolated to the center of the second).
