Classes

ComputeSourcesPointingOffset

It computes the source offset on the focal plane respect to the pointing direction.

Functions

angle_of_view(plate_scale, delta_pix, ovs)

Computes the Angle of View for a single pixel

Module Contents

class ComputeSourcesPointingOffset

Bases: exosim.tasks.task.Task

It computes the source offset on the focal plane respect to the pointing direction. The offset is in units of subpixels.

Returns:

• int – offset in the spatial direction

• int – offset in the spectral direction

execute()

Class execution. It runs on call and executes all the task actions returning the outputs. It requires the input with correct keywords

angle_of_view(plate_scale, delta_pix, ovs)

Computes the Angle of View for a single pixel

Parameters:

• plate_scale (astropy.units.Quantity) – plate scale

• delta_pix (astropy.units.Quantity) – size of a pixel

Returns:

• astropy.units.Quantity – angle of view in deg of each subpixel in the spatial direction

• astropy.units.Quantity – angle of view in deg of each subpixel in the spectral direction
