| | 1 | There are different recipes in use for stacks: |
| | 2 | |
| | 3 | THREEPI_STACK - used for LAP and SAS |
| | 4 | NIGHTLY_STACK - used for nightlyscience. |
| | 5 | |
| | 6 | For a test, I processed an MD nightlyscience (md09.20110915, i band) using the THREEPI_STACK recipe, to compare to NIGHTLY_STACK. The difference between the 2 recipes is mainly that one (threepi) puts the output in some kind of logflux way, and nightlyscience does not. |

| | 8 | I'm still processing and downloading, but I did do the following for skycell 20 (not a very clean skycell): |
| | 9 | |
| | 10 | * I looked at the catalogs mapped onto the images: psphot misses a lot for both, and detects fake things (for both) |
| | 11 | |
| | 12 | * I made a histogram plot, red= threepi_stack, black = nightly_stack. The red line looks very similar to the SAS as before, and the black looks similar in shape to skyprobe (and md). |
| | 13 | |
| | 14 | * worth noting is that the values in wt.fits for threepi are sometimes negative (what does that mean?). This does not happen in the wt.fits for the nightlystack recipe. |

| | 16 | Questions: do we need to tweak psphot to work with these logflux output files? |
