AsymmetricAnnulusPixelRegion

class regions.AsymmetricAnnulusPixelRegion(center, inner_width, outer_width, inner_height, outer_height, angle=<Quantity 0. deg>, meta=None, visual=None)

Bases: AnnulusPixelRegion

Helper class for asymmetric annuli sky regions.

Used for ellipse and rectangle pixel annulus regions.

Parameters:

centerPixCoord

The position of the center of the annulus.

centerPixCoord

The position of the center of the annulus.

inner_widthfloat

The inner width of the annulus (before rotation) in pixels.

outer_widthfloat

The outer width of the annulus (before rotation) in pixels.

inner_heightfloat

The inner height of the annulus (before rotation) in pixels.

outer_heightfloat

The outer height of the annulus (before rotation) in pixels.

angleQuantity, optional

The rotation angle of the annulus, measured anti-clockwise. If set to zero (the default), the width axis is lined up with the x axis.

metaRegionMeta or dict, optional

A dictionary that stores the meta attributes of the region.

visualRegionVisual or dict, optional

A dictionary that stores the visual meta attributes of the region.

Attributes Summary

angle	The rotation angle measured anti-clockwise as a astropy.units.Quantity angle.
center	The center pixel position as a PixCoord.
inner_height	The inner height (before rotation) in pixels as a float.
inner_width	The inner width (before rotation) in pixels as a float.
meta	The meta attributes as a RegionMeta
outer_height	The outer height (before rotation) in pixels as a float.
outer_width	The outer width (before rotation) in pixels as a float.
visual	The visual attributes as a RegionVisual.
