| Description |
|
Satoshi Hamano reports the large scale feature of dx offset in the extractionQA with the latest rerun (edr2-20231106-qa); there is generally positive (negative) offsets in right(left)-hand side of the detector. Confirm that this is real and fix the problem. Some plots are hopefully posted later. |

How are you measuring these offsets? Are they consistent with the measurements in the arcLines files? |

At the meeting, Satoshi Hamano said the positions are measured by fitting a Gaussian to the image, and then the offset is calculated as the difference with respect to the detectorMap_used. However, I've been unable to reproduce these results ( |

There are details in even Gaussian fitting. I think Satoshi Hamano should take the lead on comparing his measurements with the arcLine files. It'd be good for him to look at some DCB data too, where crowding isn't an issue. If the code isn't pushed to GitHub (presumably to tickets/ |
