The alm are given as a complex array. You can specify lmax

Parameters
----------
alm : array, complex
A complex array of alm. Size must be of the form mmax(lmax-mmax+1)/2+lmax
nside : int
The nside of the output map.
lmax : None or int, optional
Explicitly define lmax (needed if mmax!=lmax)
mmax : None or int, optional
Explicitly define mmax (needed if mmax!=lmax)
Returns
-------
m, d_theta, d_phi : tuple of arrays
The maps correponding to alm, and its derivatives with respect to
theta and phi.
