[mmaimcal] question from the Antenna Group

[Jeff Mangum]

Hi Folks,

The current Vertex antenna design models indicate that the ALMA/US
antenna will be able to turn around in 0.8 seconds assuming a 30'/sec
scan rate and a scan time of >2 seconds in OTF mode.  The Antenna
Group would like to know if this constraint is consistent with our
requirements for all of the OTF modes we envision for ALMA.  Comments?

Cheers,

Jeff
