metacal bias for crazy WCS

Thanks Mike. I'm finding that the algorithm you developed is failing for the above case. However it works if I don't reconvolve by the pixel. This is odd because in...

metacal bias for crazy WCS

(And we do expect that reconvolving by the pixel is needed)

I just copy pasted your code except for usin `dk = psf.stepk/4` which I checked is not the issue https://github.com/esheldon/ngmix/blob/51c488b0914a4499b9372875576a463e2697b29d/ngmix/metacal/metacal.py#L845

Using the default `guesser` in `Runner` construction will cause bootstrap `go()` to fail

Thanks for the reports Spencer and Arun.

I have been on vacation (still am) so I may be slow to respond. Regarding Spencer's example, we need an example using a maximum likelihood fitter. However, because the runners...

Arun, your example should have worked. Can you perhaps post a specific example in another issue?

cseg isn't that useful, I forgot it sets the default value to the id of the object rather than zero

The default is seg in the single epoch image

Are you proposing that the default change if uberseg is used for weight type?
