[mmaimcal] Re: [Almasci] Two antennas

[John Richer]

Dear Al,

Just a quick note on the article about impact of two antenna vendors on
the Science IPT costs.  It is my understanding (and someone - maybe
Robert Lucas or Christine Wilson - can correct me if I am wrong) that
the software requirements we wrote down in the SSR several years ago
already include the need to handle (polarised) beam patterns separately
for each individual antenna.  I think it is categorised in the offline
data processing requirements at the highest priority.  So I think this
work has already been costed, and cannot be put in here again as an
extra cost.  Whether such capabilites do yet exists within the offline
or pipeline packages, I cannot say.

In addition, if there is any extra cost here, it is surely mainly
against software rather than science?

Regards

John
