Dear yt-users,
I am having a little problem on finding the exact center of a halo. I used
to do
"hc = HaloCatalog(data_ds=data_ds, finder_method='hop')"
to create a halo catalog. But I think the position in the catalog is a
little bit off the exact center judging from the plots I made. I need the
exact center to compute the angular momentum so the off-center result could
cause some problem. I tried to recenter at the maximum gas density by
adding this line
"hc.sphere_field_max_recenter('density')"
But I got an error, AttributeError: 'HaloCatalog' object has no attribute
'sphere_field_max_recenter'.
Can anyone tell me what is the right way to find the center as the location
of maximum gas density?
Thanks,
Jingjing
