This is what we discussed when I visited BNL, right? Trying to remember...
@esheldon for viz
I am not seeing psf fit failures but I can try this.
Still biased with psf noise: ``` (anl) localhost:sheared_wcs_wl_sims Matt$ python run.py 100 0.1 0.0 # of sims: 100 wcs_g1 : 0.100000 wcs_g2 : 0.000000 dudx : 0.237892 dudy : -0.000000...
Hey @rmjarvis! I’ve found a weird bug in metacal that has both me and @esheldon stumped. We’ve had some discussion offline on this and are looking for your help.
So an object with hlr=3 is still biased ``` (anl) localhost:sheared_wcs_wl_sims Matt$ python run.py 100 0.1 0.0 # of sims: 100 wcs_g1 : 0.100000 wcs_g2 : 0.000000 dudx : 0.237892...
An object with hlr=0.1 is even more biased ``` (anl) localhost:sheared_wcs_wl_sims Matt$ python run.py 100 0.1 0.0 # of sims: 100 wcs_g1 : 0.100000 wcs_g2 : 0.000000 dudx : 0.237892...
Oh crap. This is the moments fitter. ``` (anl) localhost:sheared_wcs_wl_sims Matt$ python check_moments_fitter.py 100 0.1 0.1 # of sims: 100 wcs_g1 : 0.100000 wcs_g2 : 0.100000 dudx : 0.239103 dudy...
Here is a Gaussian max like fit ``` (anl) localhost:sheared_wcs_wl_sims Matt$ python check_ml_fitter.py 100 0.1 0.1 # of sims: 100 wcs_g1 : 0.100000 wcs_g2 : 0.100000 dudx : 0.239103 dudy...
Scripts that run these tests are in the same [spot](https://github.com/beckermr/misc/blob/simple-des-y3/work/sheared_wcs_wl_sims/run.py) as above.
