#8 | fixed | Polarimetry Support | ||
Description |
Support for parallactic and feed angles should be added into ASAP v2 Changes needed are: File formatParangle is currently in main table, Denoted Pa below Feed rotation is either the "angle" or "rotation" column in Focus subtable (need to check). Denoted Fr below.
The current polarisation type probably needs to be generalised a little to support single XX, YY, RR or YY Two further possible entries (has to be zero currently) for the FOCUS subtable is xyphase (measurement of the xy phase offset) and xyphase offset (position of Cal, default 0) Stokes DerivationThe existing Stokes derivations should be changed as follows to take into account paralactic and feed rotation Linear -> Circular No changed needed Linear -> Stokes Refer to Equation 10 & 11 in Simon Jonstones discussion note. For ASAP Equation 10 should be rewritten as:
Then Eqn 11 can be used where FD_HAND is "hand" in the focus table, the angles used are the sum (Pa+Fr+Pm+Pu) as defind above. If Theta=Pa+Fr+Pm+Pu
