[evlatests] Modcomp-free: L-Band

[Claire Chandler]

No, we cannot do without quack.  It is the only means we have of flagging 
bad data at the beginning of scans that would otherwise not be found. 
For example, for weak sources I determine the amount of data to be flagged 
from the calibrator scans.  It will be very painful for an 8-hour run of 
fast switching observations with 1.5 min cycle to flag everything by hand.
