class scopesim.effects.electronic.noise.PixelResponseNonUniformity(**kwargs)#

Bases: Effect

Pixel Response Non-Uniformity (PRNU).

Models the fixed pattern of per-pixel gain variations across the detector arising from manufacturing differences in quantum efficiency. Each pixel is multiplied by a gain factor drawn from N(1, prnu_std) keyed by detector ID. The gain map is generated once per detector on first use and reused identically across all subsequent exposures.

Parameters:

  • prnu_std (float or dict) – Standard deviation of the per-pixel gain distribution.

  • prnu_seed (int, fixed)

  • include ("!DET.include_prnu")

Example

  • name: prnu description: Pixel response non-uniformity class: PixelResponseNonUniformity kwargs:

    prnu_std: 0.001 prnu_seed: 42 include: “!DET.include_prnu”

Methods

__init__(**kwargs)

apply_to(obj, **kwargs)

Apply the effect to the corresponding object.

get_from_meta(item)

info()

Print basic information on the effect, notably the description.

plot([det_id])

report([filename, output, rst_title_chars])

For Effect objects, generates a report based on the data and meta-data.

apply_to(obj, **kwargs)#

Apply the effect to the corresponding object.

info() → None#

Print basic information on the effect, notably the description.

report(filename=None, output='rst', rst_title_chars='*+', **kwargs)#

For Effect objects, generates a report based on the data and meta-data.

This is to aid in the automation of the documentation process of the instrument packages in the IRDB.

Note

If the Effect can generate a plot, this will be saved to disc

Parameters:

  • filename (str, optional) – Where to save the RST file

  • output (str, optional) – [“rst”, “latex”] Output file format

  • rst_title_chars (2-str, optional) – Two unique characters used to denote rst subsection headings. Options: = - ` : ‘ “ ~ ^ _ * + # < >

  • parameters (Additional)

  • ---------------------

  • **kwargs (Either from the self.meta["report"] dictionary or via)

  • "report_table_include" (False)

  • "report_table_caption"

  • "report_plot_caption"

  • "report_plot_include" (False)

  • "report_plot_file_formats" (["png"]) – Multiple formats can be saved. The last entry is used for the RST.

  • "report_plot_filename" (None) – If None, uses self.meta[“name”] as the filename

  • "file_description" (str) – Taken from the header of a file, if available

  • "class_description" (str) – Taken from the docstring of the subclass

  • "changes_str" (list of str) – Take from the header of a file, if available

Returns:

rst_str – The full reStructureText string

Return type:

str

Notes

The format of the RST output is as follows:

<ClassType>: <effect name>
**************************
File Description: <description for file meta data>
Class Description: <description from class docstring>
Changes: <list of changes from file meta data>
