healpy.query_strip(nside, theta1, theta2, inclusive=False, nest=False, ndarray buff=None)

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.

nside : int

The nside of the Healpix map.

theta1 : float

First colatitude (radians)

theta2 : float

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

ipix : int, array

The pixels which lie within the given strip.
