healpy.fitsfunc.write_alm¶
- healpy.fitsfunc.write_alm(filename, alms, out_dtype=None, lmax=-1, mmax=-1, mmax_in=-1, overwrite=False)¶
Write alms to a fits file.
In the fits file the alms are written with explicit index scheme, index = l*l + l + m +1, possibly out of order. By default write_alm makes a table with the same precision as the alms. If specified, the lmax and mmax parameters truncate the input data to include only alms for which l <= lmax and m <= mmax.
- Parameters:
- filenamestr
The filename of the output fits file
- almsarray, complex or list of arrays
A complex ndarray holding the alms, index = m*(2*lmax+1-m)/2+l, see Alm.getidx
- lmaxint, optional
The maximum l in the output file
- mmaxint, optional
The maximum m in the output file
- out_dtypedata type, optional
data type in the output file (must be a numpy dtype). Default: alms.real.dtype
- mmax_inint, optional
maximum m in the input array
