When running reduceExposure.py with doMeasureLines=True, an apparent failure to measure aperture corrections leads to the processing failing. In many cases I don't care about the photometry (e.g. if I'm looking at focal plane distortions). For now setting the appCorr to NaN and proceeding might be acceptable. Setting the aperture correction to 1.0 would require that we signal this failure to the user in some other way.
E.g. the command
reduceExposure.py /work/drp --calib /work/drp/CALIB --rerun rhl/calibrations-2023-07-v6 -c isr.doFlat=False isr.doFlatNir=True isr.doDark=False useCalexp=True doAdjustDetectorMap=False doMeasureLines=True --id visit=96958 arm=r spectrograph=1
fails with:
