starepandas.STAREDataFrame.trixel_corners

STAREDataFrame.trixel_corners(vertices=None, from_trixels=False)

Returns corners of trixels as lon/lat.

If vertices is set, the trixel corners are extracted from vertices (c.f. trixel_vertices()). If from_trixels is True and dataframe contains trixel column, corners are extracted from trixels. If not, corners are generated from stare column

Parameters

verticestuple (vertices data structure)

If set, the centers are extracted from the vertices.

from_trixels: bool

If true and dataframe contains trixel column, corners are extracted from trixels.

Returns

cornersnumpy array

Corners of the trixels in lon/lat representation. First dimension are the SIDs, second dimension the corners (1 through 3), third dimension lon/lat.

Examples

>>> sids = numpy.array([3458764513820540928])
>>> df = starepandas.STAREDataFrame(sids=sids)
>>> df.trixel_corners()
