failed to choose a psf model for PSPHOT.STACK.OUTPUT.IMAGE entry 1

The root cause of the assert is that psphotStackReadout does not insure that psphotChoosePSF succeeds before proceeding in the radial apertures loop.

psphotResetModels expects the psf to exist on readout->analysis and pops the assertion.

The reason that psphotChoosePSF is failing is that none of the apMag values in pmGrowthCurveGenerate measured are finite.

I'll update the code to check before calling psphotVectorStats and print a better error message.

The error happens when working on the g band input convolved stack from stack 1068530 after convolving to 6pixel fwhm. The input image looks pretty bad the further convolved image looks worse.

There is a lot of ringing from deconvolution.

This error is seen in 8 of LAP staticsky runs out of the 60000 run so far
