Methods Documentation

to_pixel(wcs)

Return a pixel region from this sky region.

Parameters:

wcsWCS object

A world coordinate system (WCS) transformation that supports the astropy shared interface for WCS (e.g., astropy.wcs.WCS).

as_ellipsebool, optional

If True, return an EllipsePixelRegion instead of a CirclePixelRegion. An ellipse is generally a better approximation when the WCS has distortions or different pixel scales along different axes. Default is False.

Returns:

regionCirclePixelRegion or EllipsePixelRegion

The pixel region. An ellipse is returned if as_ellipse is True.
