size_holes_nest
Arguments appearing in italic are optional.call size_holes_nest( nside, mask, nholes, nph, [tags, sizeholes, listpix] )
name & dim. | kind | in/out | description |
---|---|---|---|
nside | I4B | IN | The Nside value of the input mask. |
mask(0:Npix-1) | I4B | IN | Input binary NESTED-ordered mask. Npix = 12*nside*nside |
nholes | I4B | OUT | Number of holes found |
nph | I4B | OUT | Number of pixels in holes |
tags(0:Npix-1) (OPTIONAL) | I4B | OUT | Pointer allocated by size_holes_nest, containing a sky map in which invalid pixels belonging to the largest hole have value -1, those belonging to the second largest hole have value -2, and so on, while valid pixels keep value +1. |
sizeholes(0:nholes-1) | I4B | OUT | Pointer allocated by size_holes_nest, containing on output the respective size of each hole (in decreasing order). Eg, sizeholes(0) is the number of pixels in the largest hole (taking value -1 in tags). |
listpix(0:nholes+nph) | I4B | OUT | Pointer allocated by size_holes_nest, containing on output the indexed list of pixels in each hole. Pixels located in the first (and largest) hole are given by listpix(listpix(0):listpix(1)-1) |
