| 736 | | Want to look at NOT setting the convolved stack target PSF based on the worst input. Have seen cases when the worse inputs are image rejected so in that case not a good idea to use anyways. |
| 737 | | * for large N, a rerun would be of little time cost or just reject outright as little input to final stack |
| 738 | | * for small N may want to reject anyways |
| 739 | | * instead of a rerun of target psf, could choose median psf or such and use poorer deconvolution to reject worse images anyways |
| | 736 | Want to look at not necessarily setting the convolved stack target PSF driven by what appears to be the worst input. Have seen cases when the worse inputs are image rejected so in that case not a good idea to use anyways. |
| | 737 | * for large N, a rerun would be of little time cost or just reject outright as little input to final stack? Not full run but additional clipping of outliers more before convolving. |
| | 738 | * for small N may want to reject anyways? Adding poorest image versus dropping 20-30% of possible inputs? |
| | 739 | * instead of a rerun of target PSF, could choose mean/median PSF or an optimal and use poor deconvolution to reject worse images? |
| 744 | | * will need to make a sample distribution of simulated PSFs, currently sample is flat. revise the making of the stack.mdc list of inputs. or will just be worse/upper limit of possible stack degrading for including deconvolved images. |

| 746 | | SYS.ERR=0 change set, but effect comes after this stage so not important. |

| 748 | | MD04 skycell.055,058 samples for deep stacks. Current operating FWHM cut is at 7.5 pixels, generally excluding <10% of all available warps. |

| | 749 | Same test sets as describe above ([wiki:ppStack_testing_201111#TestSets]) |
| | 750 | * Simtest sample |
| | 751 | |
| | 752 | * MD04 sample: |
| | 753 | * for sub-samples (N=20, 100) of MD04s055 |
| | 754 | * skycell.055,058 full test samples for deep stacks: Current operating FWHM cut is at 7.5 pixels, generally excluding <10% of all available warps. |
