s2let_mw2hpx

PURPOSE ^

s2let_mw2hpx

SYNOPSIS ^

function f_hpx = s2let_mw2hpx(f, nside, varargin)

DESCRIPTION ^

 s2let_mw2hpx 
 Converts MW map into Healpix map

 Default usage :

   f_hpx = s2let_hpx2mw(f_mw, <options>)

 f is the input map -- MW sampling,
 f is the output map -- Healpix sampling.

 Option :
  'L'               = { Harmonic band-limit; L > 1 (default=guessed) }
