| | 1812 | * (left) Sample histogram of the available exposures by camera FWHM_MAJOR in i-band (red) and selected to attempt a deepstack with (blue) in top row, refstack in bottom row. |
| | 1813 | * (right) Sample histograms for each skycell over the FPA by FWHM of the input warps in the i-band (blue) and rejected for poor PSF (red). The black dotted line is the input cut @7.5 pixels and the red line is the FWHM_mean+1.5*FWHM_SIGMA additional cut on the input FWHM that is often ~6 pixels given the available input warps -- initially set in an attempt to restrict the target PSF of the convolved version of the stack to ~1.5" but other problem(s) still exist that drive the target PSF much larger. |
