Hi Amy-<br />
<br />
I hope you’re and your family are doing well. <br />
<br />
Thanks for looking into this. As I have been able to make the corrections by downloading the latest USNO file and applying CLCOR I’m set. <br />
<br />
However, I have a separate problem. Both in the raw data and in amplitude calibrated data the RR and LL amplitudes on most baselines differ systematically and sometimes significantly. I have not looked at fringe fit data yet...(the source certainly has no significant circular polarization).<br />
<br />
Is this a common problem with the VLBA? Is there a simple way to “fix” this? <br />
<br />
Thanks,<br />
<br />
Dave<br />
