For interpolated beams (EMSS beams and such), investigate the possibility of improving the frequency interpolations as follows:
- say we're interpolating at point l,m,f, and f lies between frequency planes f1 and f2. The current implementation interpolates both planes at l,m, then takes a weighted mean of the values.
- Instead, interpolate the f1 plane at l1=l(f1/f),m1=m(f1/f). Interpolate the f2 plane at l2=l(f2/f),m2=m(f2/f), and then take the same weighted mean.
