query_disc
call query_disc( nside, vector0, radius, listpix, nlist [, nest, inclusive] )
name & dimensionality | kind | in/out | description |
---|---|---|---|
nside | I4B | IN | the
![]() |
vector0(3) | DP | IN | cartesian vector pointing at the disc center. |
radius | DP | IN | disc radius in radians. |
listpix(0:*) | I4B/ I8B | OUT | the index for all pixels within radius. Make sure that the size of the array is big enough to contain all pixels. |
nlist | I4B/ I8B | OUT | The number of pixels listed in listpix. |
nest (OPTIONAL) | I4B | IN | The pixel indices are in the NESTED numbering scheme if nest=1, and in RING scheme otherwise. |
inclusive (OPTIONAL) | I4B | IN | If set to 1, all the pixels overlapping (even partially) with the disc are listed, otherwise only those whose center lies within the disc are listed. |
Returns the NESTED pixel index of all pixels north of the equatorial line in amap.
