[daip] frequency

[Crystal Brogan]

Hi Eric,

I have an sma observation that was doppler tracked at the
wrong LSR velocity. Thus both the velocities and frequencies
are off.

I have another day of data from which I know what the "real frequency" of
the first channel should be (this is the ref. pix). Call this one day1 and
the bad one day2

I have tried the following:

* changing crval(3) in day 2 to match day 1

* changing AN file so that the frequency listed there is the
same in day2 as day1 AND changing the header

Neither of which have worked. Line shows up at same wrong
place when I image.

Can you recommend a way to do this? I thought maybe UVFIX
but it doesn't let me specify the freq. with enough accuracy:
3.4197260E+11 GHz.

Thanks,
crystal
