<p>The issue is with the computation of aberation. That has a very very small effect.</p>
<p>Set UVFIXPRM(18) = 1 and the issue will not arise. Alternatively, run UVFIX on</p>
<p>the output of UVFIX and that will also correct everything. I will now try to find out</p>
<p>how to fix this issue.... There is also a calibration issue in my reduction but that</p>
<p>may be a user error (I make them too). I will look in a bit.</p>
