Classes#

CreateIntrapixelResponseFunction

It creates the intrapixel response function to be used in the convolution with the focal plane array.

Module Contents#

class CreateIntrapixelResponseFunction[source]#

Bases: exosim.tasks.task.Task

It creates the intrapixel response function to be used in the convolution with the focal plane array.

Returns:

  • kernel (2D array) – the kernel image

  • kernel_delta (scalar) – the kernel sampling interval in microns

Notes

This is a default class with standardised inputs and outputs. The user can load this class and overwrite the “model” method to implement a custom Task to replace this.

execute()[source]#

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

model(parameters)[source]#

This model creates the intrapixel response function to be used in the convolution with the focal plane array. Thsi intrapixel response function is compatible with the Scipy convolution functions.

Estimate the detector pixel response function with the prescription of Barron et al., PASP, 119, 466-475 (2007).

Parameters:

  • oversampling (int) – number of samples in each resolving element. The final shape of the response function would be shape*osf

  • delta_pix (astropy.units.Quantity) – Phisical size of the detector pixel in microns

  • diffusion_length (astropy.units.Quantity) – diffusion length in microns

  • intra_pix_distance (astropy.units.Quantity) – distance between two adjacent detector pixels in microns

Returns:

  • kernel (2D array) – the kernel image

  • kernel_delta (astropy.units.Quantity) – the kernel sampling interval in microns
