meanOmega
(dangle, oned=False, offset_sign=None, tdisrupt=None)¶ NAME:
meanOmegaPURPOSE:
calculate the mean frequency as a function of angle, assuming a uniform time distribution up to a maximum timeINPUT:
dangle - angle offset
oned= (False) if True, return the 1D offset from the progenitor (along the direction of disruption)
offset_sign= sign of the frequency offset (shouldn’t be set)
