---|---|---|---|
nside | I4B | IN | the Nside parameter of the map. |
iz | I4B | IN | ring number, counted southwards from the north pole. |
phi0 | DP | IN | central ![]() |
dphi | DP | IN | defines the size of the slice. The slice has length 2 x dphi along the ring with center at phi0. |
listir(0:4*nside-1) | I4B/ I8B | OUT | The pixel indexes in the slice. |
nir | I4B | OUT | the number of pixels in the slice. nir
![]() |
nest (OPTIONAL) | I4B | IN | The pixel indexes are in the NESTED numbering scheme if nest=1, and in RING scheme otherwise. |
