Description

Can the following gain curve be added to ASAP for Parkes (K-band). Questions regarding the polynomial form should be directed to John Reynolds

The current curve for K-band (22.235GHz) is: 

     Gain = 0.210528
               +0.296759E-01 * El
               -0.293124E-03 * El^2
               +0.264295E-06 * El^3

where El is elevation in degrees. The curve has a peak normalised to 1.00 (at an El of close to 55 degrees), and has approximate values of 0.845 at 30 degrees El, and 0.70 at 90 degrees El (useful as a sanity check).

Chris,

I have put this in. This assumes the Antenna Name being ATPKSHOH. If the Antenna Name is different one has to use scantable.set_instrument('ATPKSHOH') to gain access to the curves.

I have asked Warwick to look into the Antenna/Reciver names and put them into rpfits properly.
