[Difx-users] Question on changing data rates during observation {External} {External}

[Geoff Crew]

If what was done is consistent with the experiment vex.obs file, then 
""the is answer is no", but:

It depends a bit on what you mean about recording rates.  If you are 
switching the recording setup, then you will need a mode (for all 
stations) that explains what mode on the relevant scans was used.

If you are dropping half of the data on the floor, results will depend 
on what you actually dropped.

DiFX can't read anyone's mind or reverse engineer crazy things that 
happen in the field.  That is always what the operators have to deal 
with....
