get_healpix_weight_file, $\ldots$

Functions are available to return the standardized name of pre-generated FITS files required by some HEALPix facilities and subroutines. Those files are available in the data subdirectory, whose full path is returned by companion functions such as get_healpix_data_dir.

Location in HEALPix directory tree: src/f90/mod/paramfile_io.F90 

FUNCTIONS:
winfile = get_healpix_pixel_window_file(nside)

returns, for the nside provided, the name of the FITS file containing the window function associated with the HEALPix pixel (of the form pixel_window_n*.fits).

w8file = get_healpix_weight_file(nside, won)

returns the name of the FITS file containing the ring-based or pixel-based weights for the given HEALPix resolution parameter nside. If won $= 1$, the output of get_healpix_ring_weight_file(nside) is returned, while if won $= 2$, it is the output of get_healpix_pixel_weight_file(nside). won$=0$ will return an empty string, while other choices of won will result in errors.

w8rfile = get_healpix_ring_weight_file(nside)

returns, for the nside provided, the name of the FITS file containing the ring-based weights (of the form weight_ring_n*.fits).

w8pfile = get_healpix_pixel_weight_file(nside)

returns, for the nside provided, the name of the FITS file containing the pixel-based weights (of the form weight_pixel_n*.fits). Some of them (for power of 2 nside in $[16,2048]$) are located in the data directory, the other ones can be generated with the compute_weights C++ facility.
