| | 43 | Gene has stacked these u band before (in eamMC database). I copied his database to 'megacam', and updated the schema. I've tried stacking by lunation for JT, with mixed results: |
| | 44 | |
| | 45 | * there are quite a few skycells with bad astrometry |
| | 46 | * all of MD06 has bad astrometry |
| | 47 | * some do not have good coverage - I may need to stack multiple lunations to get it |
| | 48 | * quite a few of the images have bad crosstalk - this is present in the initial images from CADC, but not present in the stacks (does this just get averaged out?) |
| | 49 | |
| | 50 | Things that I need to do to get it working properly |
| | 51 | |
| | 52 | * work on the astrometry - Gene has a few suggestions which I will try to implement |
| | 53 | * make some more stacks (for tests) |
| | 54 | * do I need to filter out the bad astro? |
| | 55 | * stack together a few lunations - does this improve? |
| | 56 | * stack together all lunations - does my stack look similar to Gene's stacks (his is from much older code) |
