 Description   

The current official calib, CALIB-20211220, contains detectormaps that have zero slit offsets for each fiber.

Please regenerate a set of new CALIBS ensuring that the parameter fitDetectorMap.doSlitOffsets=True.

New set of calibs including r and b detector maps with non-zero slit offsets generated under name CALIB-20220615. This is available under tiger (directory /projects/HSC/PFS/Subaru/CALIB-20220615), Summit /work/CALIB-20220615 and Hilo (/data/drp/sm1-5.2/CALIB-20220615). Example residuals for reduceExposure runs for b and r are shown as and respectively. Residuals in general < 0.1 pixels, although a few misidentified lines for r apparent. Improvement with adjusting slits apparent whe comparing (which is generated with the previous CALIB-PFI-20211220 that had zero slit offsets) and which is generated using CALIB-20220612. The vertical stripes are much less apparent.

Fit summaries of reduceArc runs below for b:

reduceArc.fitDetectorMap INFO: Final fit: chi2=287508.313571 dof=143226 xRMS=0.051771 yRMS=0.045524 (0.003104 nm) xSoften=0.032428 ySoften=0.027441 from 71685/71815 lines

and for r:

reduceArc.fitDetectorMap INFO: Final fit: chi2=375064.971505 dof=238474 xRMS=0.054415 yRMS=0.049705 (0.004291 nm) xSoften=0.026536 ySoften=0.022774 from 119309/119464 lines

Note that an m-band detectormap is not available yet due to time constraints. I aim to address this as part of PIPE2D-986 at the end of June 2022.
