After the telescope collapse

  monitor the stability of the platform and azimuth sitting in the dish.

Tower 4  cable failures

Major events that impacted the telescope.

Telescope calibration:

    gain curves
    sefd curves
    system performance (all receivers)
    cal values

Telescope calibration:

  1. Multi frequency measurements.

  2. System performance multi freq. measurements.
    Compare gain/sefd sep00, aug02 (dec02)
    Comparison of gain before and after reflector adjusted  (CTA21,C3138) (mar02)
    Tsys vs turret offset for lbw, lbn, sbn, sbw,cband,and xband (feb02).
    Gain and Sefd for multiple receivers using 3C48 and 3C138 (dec01)
    Pitch, roll, focus correction at multiple frequencies on 3C48, CTA21 (feb01)
    CTA21 sefd, tsys, and gain at lband, sband, and cband (aug00)
  3. Temperature dependence.
