List of in-region patches for DC1-phoSim-3a Level 2 outputs #35

Closed jchiang87 closed 7 years ago

Here is the list of patches that intersects our nominal DC1 region: phosim_DC1_region_patches.txt

Here's a plot showing the four patch selections (full phoSim-3a, trimmed phoSim-3a, imsim undithered, imsim dithered):

dc1_tract_patch_l2_coverage

The script that generated the patch list and that plot is here.

It was determined that this was due to a mismatch in convention between the rotational conventions of CatSim and PhoSim as described in issue #36.

The effect was to make the camera rotate the wrong way in PhoSim causing the chips to be outside of our desired area. This approximately quadrupled our exposed area while keeping the number of visits fixed. Therefore the depth is not-constant over the entire region, being especially reduced on the edges.
