Need custom stamp type `BalStamp` to process GalSim runtime errors #69

Closed sweverett closed 5 years ago

sweverett commented 5 years ago

The deep-field catalog contains too many spurious objects that request huge (100k x 100k) FFT grids. It is not straightforward to cut these objects w/o biasing selection, so instead we should (1) stick with a reasonable max_fft_size, (2) create a custom stamp type that skips a stamp if there is a runtime error, and (3) records the failure somewhere convenient.
