Description
When using psfex to model the PSF, if the config parameter controlling the order of the spatial variation of the fit is set to 0, a Segmentation fault occurs. This should be avoided by either fixing the code or explicitly disallowing this setting, whichever is most appropriate.
The there is a check that the value for this parameter is >=0 here:
https://github.com/lsst/meas_extensions_psfex/blob/master/python/lsst/meas/extensions/psfex/psfexPsfDeterminer.py#L43-L48
so if the latter option is opted for, the check could just be for >0.
How to reproduce with obs_subaru HSC data:
Include the following config setting
config.charImage.measurePsf.psfDeterminer["psfex"].spatialOrder = 0 |
e.g. with a file config.txt with the above line in it.
Then run:
processCcd.py /datasets/hsc/repo/ --rerun private/yourRepo --id visit=1228 ccd=49 -C config.txt |
Traceback looks like:
