| | 17 | * Reported results of psphotStack photometry to DRAVG. Many questions. |
| | 18 | * The data shows that the psphotStack measurements based on the morphology of objects like the Kron measurements and the model fits show better results when using the unconvolved stacks. |
| | 19 | * There is an offset between SDSS stripe 82 psf magnitudes and psphotStack when a Gaussian psf model is used. A smaller offset results using the PS_MODEL_PS1_V1 |
| | 20 | * The scatter in the kron magnitudes appears to be larger than with psphot. This turned out to be due to a bug in the code causing sources with bad moments to be measured. |
| | 21 | * Implemented and tested a feature that limits the kron integration area based on the surface brigthness of the source. With this change the kron radii are much better behaved. |
| | 22 | * Based on all of the above we have updated the psphot recipes and code and created a new operational tag. Time for SAStest.v5 |
