Module Contents

class ComputeSubFrgSignalsChannel

Bases: exosim.tasks.task.Task

It iteratively estimates the radiometric signals on the foregrounds sub focal planes for a channel and returns a table with all the contributions.

Returns:

signal table

Return type:

astropy.table.QTable

Raises:

TypeError: – if the output is not QTable

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()

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

model(ch, table, input_file, parameters)

It iteratively estimates the radiometric signals on the foregrounds sub focal plane for a channel and returns a table with all the contributions. It uses photutils.aperture.aperture_photometry with the apertures from EstimateApertures.

Parameters:

• table (astropy.table.QTable) – apertures table

• ch_name (str) – channel name

• input_file (Output) – input HDF5 file

• parameters (dict) – dictionary contained the channel parameters. This is usually parsed from LoadOptions

Returns:

signal table

Return type:

astropy.table.QTable
