Should not have deferred to engineers.</p> <p>Undo change before NIR data becomes any more public. Added a W_4FMTVR card to signal such changes. Will be 2 after this change.</p> INSTRM-1349

Undo INSTRM-940 flip across Y.

That's OK, but I'd like to be sure.</p> <p>Please identify visits with correct headers from before and after this change which are visible in Princeton (and anywhere else that might care). I can handle this transparently in the code, but will want to be able to check.</p> <p>"Handle" probably means apply this unflip to old raw data, and flip new post-ISR data. </p> <p>The main physical difference between vis and nir cameras is that dispersion is along rows for the nir cams. </p> <p>I believe that by undoing the <a href="https://pfspipe.ipmu.jp/jira/browse/INSTRM-940" title="Flip H4 x-axis at readout" class="issue-link" data-issue-key="INSTRM-940"><del>INSTRM-940</del></a> flip, the main difference between the vis and nir geometry will be just that: a +/- <img class="emoticon" src="https://pfspipe.ipmu.jp/jira/images/icons/emoticons/help_16.png" height="16" width="16" align="absmiddle" alt="" border="0"/> 90 degree rotation. No other flips, etc. Well, except for the different channel/amp geometries and the fact that there really is only one H4 chip, not two CCDs.</p> Development Rank 0|zzs90o: Story Points 1.0
