query_strip
call query_strip( nside, theta1, theta2, listpix, nlist, nest )
name&dimensionality | kind | in/out | description |
---|---|---|---|
nside | I4B | IN | the Nside parameter of the map. |
theta1 | DP | IN | colatitude lower bound in radians measured from North Pole
(between 0 and ![]() |
theta2 | DP | IN | colatitude upper bound in radians measured from North Pole (between 0 and ![]() ![]() |
listpix(0:*) | I4B | OUT | the index for all pixels enclosed in the strip(s). Make sure that the size of the array is big enough to contain all pixels. |
nlist | I4B | 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. |
Returns the NESTED pixel index of all pixels with colatitude in [0,/5] and those with colatitude in [3
/4,
