SkyRegion

class regions.SkyRegion

Bases: Region

Base class for all regions defined in celestial coordinates.

Methods Summary

contains(skycoord, wcs)	Check whether a sky coordinate falls inside the region.
intersection(other)	Return a region representing the intersection of this region with other.
symmetric_difference(other)	Return the union of the two regions minus any areas contained in the intersection of the two regions.
to_pixel(wcs)	Return the equivalent region defined in pixel coordinates.
union(other)	Return a region representing the union of this region with other.

Methods Documentation

contains(skycoord, wcs)

Check whether a sky coordinate falls inside the region.

Parameters:

skycoordSkyCoord

The position or positions to check.

wcsWCS

The world coordinate system transformation to use to convert between sky and pixel coordinates.

intersection(other)

Return a region representing the intersection of this region with other.

Parameters:

otherRegion

The other region to use for the intersection.

symmetric_difference(other)

Return the union of the two regions minus any areas contained in the intersection of the two regions.

Parameters:

otherRegion

The other region to use for the symmetric difference.

abstract to_pixel(wcs)

Return the equivalent region defined in pixel coordinates.

Parameters:

wcsWCS

The world coordinate system transformation to use to convert between sky and pixel coordinates.

Returns:

pixel_regionPixelRegion

A pixel region.

union(other)

Return a region representing the union of this region with other.

Parameters:

otherRegion

The other region to use for the union.
