Hi Chris, difx-users,<br>
<br>
I've performed a couple relatively simple tests comparing 2.6.2 to 2.6.3 <br>
at a level that I think is appropriate for the types of changes between <br>
these two releases and all looks good. Things I looked at are:<br>
<br>
1. 4-channel multi-thread VDIF using dual-band (S/X), single scan<br>
<br>
2. 16-channel Mark5B with multiple scans<br>
<br>
3. verified phase, delay, amplitudes, and bandpasses look good<br>
<br>
4. assessed that noise levels are comparable<br>
<br>
5. verified that extracted pulse cal is unchanged<br>
<br>
6. verified that data completeness (visibility and other tables) is unchanged<br>
<br>
Note that these tests are fairly well focused on "usual" VLBA science data <br>
sets. They do not include:<br>
<br>
* complex data of any kind<br>
<br>
* geodetic analysis<br>
<br>
* mismatched / zoom bands<br>
<br>
* polarization conversion<br>
<br>
* multi-phase-center<br>
<br>
It would be good if some other folks could run some tests focusing on some <br>
of these areas.<br>

>> Please test and report back before Friday 5th November. As this stage I would consider the branch in a slushy freeze state. Please do not add new features etc, but we will fix any bugs found. I would like to freeze the code on Monday 8th November (Australian
time!) if no problems are found.<br>
