nside |
I4B |
IN |
The 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) |
