I’m following the tutorial at pipelines.lsst.io and am trying to implement forced photometry on individual exposures with forcedPhotCcd.py. All the stages of the tutorial up to and including doing the photometry on the coadds with forcedPhotCoadd.py have run successfully. When I run the following commands
forcedPhotCcd.py $DATADIR --rerun coaddPhot:ccdForcedPhot --id filter=HSC-R &> r_band_output.txt forcedPhotCcd.py $DATADIR --rerun ccdForcedPhot --id filter=HSC-I &> i_band_output.txt
the output includes the following error:
FatalAlgorithmError: CModel forced measurement currently requires the measurement image to have the same Wcs as the reference catalog (this is a temporary limitation)
I am running on a spawned machine on
lsst-lspdev with version 16 of the stack. I’m unsure why the measurement image apparently doesn’t have the same WCS as the reference catalog because I made a skymap for the exposures following the tutorial.
The end result is that forcedPhotCcd.py writes an empty table to
forced_src_schema.fits and no other FITS files. Does anyone know what might help here?
