query_strip
()¶ Returns pixels whose centers lie within the colatitude range defined by theta1 and theta2 (if inclusive is False), or which overlap with this region (if inclusive is True). If theta1<theta2, the region between both angles is considered, otherwise the regions 0<theta<theta2 and theta1<theta<pi.
- Parameters
- nsideint
The nside of the Healpix map.
- theta1float
First colatitude (radians)
- theta2float
Second colatitude (radians)
- inclusive ; bool
If False, return the exact set of pixels whose pixels centers lie within the region; if True, return all pixels that overlap with the region.
- nest: bool, optional
if True, assume NESTED pixel ordering, otherwise, RING pixel ordering
- buff: int array, optional
if provided, this numpy array is used to contain the return values and must be at least long enough to do so
- Returns
- ipixint, array
The pixels which lie within the given strip.
