I believe that this data should have been properly aligned, even thought they had the wrong stop (F/3.3)</p> <p>This ticket is to 1. investigate this claim, 2. see if this is still the case in the data taken with the F/2.8 stop .</p> PIPE2D-424

Investigate very wide traces

I have verified that the traced indeed look different and that the analysis done by <a href="https://pfspipe.ipmu.jp/jira/secure/ViewProfile.jspa?name=price" class="user-hover" rel="price">price</a> is correct.</p> <p>2. The reason for the error is that the flats have been taken with setting <tt>W_ENFCAX= -0.5 / FCA X coordinate</tt>, as tracked in the header. This is because the value for W_ENFCAX was not reset, after taking dithered data. I have verified that the data taken beforhand (darks and biases, e.g., 13182) have also <tt>W_ENFCAX= -0.5 / FCA X coordinate</tt>. As such, this config data is not usable. </p> Relates PIPE2D-415 Development Rank 0|zx00fk: Reviewers hassan Story Points 2.0
