mkpsf failed on the scrambled image.

Error: The cog model fit did not converge
Invalid mkapfile output? (check ./1667873s12.mkap)
failed to build psf

perhaps copy psf from non-scrambled version.

closing this because the 13BH processing is being restarted from scratch.

The PSF failing to get a COG was the result of using too high a threshold for step2jmp. the maximum linearity threshold is set to 20,000. This avoids any chance of having saturated stars in the PSF. 20,000 is bright enough for good SNR PSF.
