[yt-users] Covering Fraction / Solid angle

[Elizabeth Harper-Clark]

Hi Guys,

Is there a way to quantify values in yt by solid angle around a point?

For example I have a simulation of star clusters forming within a turbulent
GMC. When a bubble is present I want to calculate the covering fraction of
the shell. One way to do this would be using where the radiation pressure is
absorbed and calculate the fraction of solid angle (around the oldest
cluster) radiation pressure is absorbed above a minimum value out to a given
radius. See attached for projections of this simulation at a time with a
bubble shell! (bottom left shows radiation pressure absorption).

Has anyone written any code/script to calculate solid angle before?

Many thanks,

Libby
