Hi Chris,

Yes, if you can point me to the fits file for the B_l's, that would be
great.  I have only prepared input maps following a pretty limited set
of recipes, with circular Gaussian beams, so I'm not very familiar with
the other options that are available in alteralm.  I take it that the
fits file you mention is a file with beam properties only, which can be
applied to any healpix map as a way of performing the beam smoothing?

If we get this working, it sounds as though it would be preferable to
(as John says) make it the standard for abscal.  In that case I will
just drop the abscal sims I've been running with circular Gaussian
beams.
