name&dimensionality | kind | in/out | description |
---|---|---|---|
nside | I4B | IN | the
![]() |
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/ I8B | 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/ 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 strip are listed; otherwise only those whose center lies within the strip are listed. |
Returns the NESTED pixel index of all pixels with colatitude in [0,] and those with colatitude in [
