STIXImaging

class stixpy.coordinates.frames.STIXImaging(*args, **kwargs)

Bases: SunPyBaseCoordinateFrame

STIX Imaging Frame

• Tx (aka “theta_x”) along the pixel rows (e.g. 0, 1, 2, 3; 4, 5, 6, 8).

• Ty (aka “theta_y”) along the pixel columns (e.g. A, B, C, D).

• distance is the Sun-observer distance.

Aligned with STIX ‘pixels’ +X corresponds direction along pixel row toward pixels 0, 4 and +Y corresponds direction along columns towards pixels 0, 1, 2, 3.
