SDS_MASKS(3)
NAME
sds_masks: Generates sets of spherical-harmonic values
SYNOPSIS
#include <soi_fun.h>
int sds_masks ( l_min, l_max, delta_m, fft_rows, z_max,
mask_file_name, masks)
int l_min, l_max;
int delta_m;
int data_rows;
double z_max;
char * mask_file_name;
SDS * masks;
DESCRIPTION
sds_masks() Generates values for spherical harmonics
Y_lm(z) from z=0 to z=z_max. in increments calculated from
the number of samples for each mode: data_rows. The degree
ranges for l_min through l_max in steps of one. The order
ranges from l_min through l_max in steps of delta_m.
The function does not return data;, it writes it to a file:
"mask_file_name." The reason for this is DEC's limit on
memory. Large mask files cannot be stored in virtual
memory. A "segmentation fault" would occur.
STATUS
The tested program, which did compile at one time, no longer
compiled due to changes in SDS. The current version, which
compiles, has never been run.
