name & dimensionality | kind | in/out | description |
---|---|---|---|
in_map(0:npix-1) | SP/ DP | IN | Full sky HEALPix map to filter. npix should be valid HEALPix pixel number. |
radius | DP | IN | Radius in RADIANS of the disk on which the median is computed. |
med_map(0:npix-1) | SP/ DP | OUT | Median filtered map: each pixel is the median of the input map valid neighboring pixels contained within a distance radius |
nest OPTIONAL | I4B | IN | set to 1 if the map ordering is NESTED, set to 0 if it is RING. |
fmissval OPTIONAL | SP/ DP | IN | sentinel value given to missing or non-valid pixels. Default: HPX_SBADVAL or HPX_DBADVAL |
fill_holes OPTIONAL | LGT | IN | if set to .true. will replace non-valid pixels by median of neighbors; if set to .false. will leave non-valid pixels unchanged. Default: .false. |
Output in med the median filter of map, using a filter radius of 0.5 Deg
