Methods

__init__(**kwargs)

apply_to(det, **kwargs)

Apply to detector readout.

get_from_meta(item)

info()

Print basic information on the effect, notably the description.

make_spectral_traces()

Return a dictionary of spectral traces read in from a file.

plot([wave_min, wave_max, axes])

rectify_cube(hdulist)

Rectify traces and combine into a cube.

rectify_traces(hdulist[, xi_min, xi_max, ...])

report([filename, output, rst_title_chars])

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

update_meta()

Update fov related meta values.

Attributes

data

display_name

footprint

Return the footprint of the entire SpectralTraceList.

image_plane_header

Create and return header for the ImagePlane.

include

meta_string

report_plot_include

report_table_include

table

z_order

apply_to(det, **kwargs)#

Apply to detector readout.

property footprint#

Return the footprint of the entire SpectralTraceList.

property image_plane_header#

Create and return header for the ImagePlane.

info() → None#

Print basic information on the effect, notably the description.

make_spectral_traces()#

Return a dictionary of spectral traces read in from a file.

plot(wave_min=None, wave_max=None, axes=None, **kwargs)#

Plot every spectral trace in the spectral trace list.

Parameters:

  • wave_min (float, optional) – Minimum wavelength, if any. If None, value from_currsys is used.

  • wave_max (float, optional) – Maximum wavelength, if any. If None, value from_currsys is used.

  • axes (matplotlib axes, optional) – The axes object to use for the plot. If None (default), a new figure with one axes will be created.

  • **kwargs (dict) – Any other parameters passed along to the plot method of the individual spectral traces.

Returns:

fig – DESCRIPTION.

Return type:

matplotlib figure

rectify_cube(hdulist)#

Rectify traces and combine into a cube.

rectify_traces(hdulist, xi_min=None, xi_max=None, interps=None, **kwargs)#

Create rectified 2D spectra for all traces in the list.

This method creates an HDU list with one extension per spectral trace, i.e. it essentially treats all traces independently. For the case of an IFU where the traces correspond to spatial slices for the same wavelength range, use method rectify_cube (not yet implemented).

Parameters:

  • hdulist (str or fits.HDUList) – The result of scopesim readout()

  • xi_min (float [arcsec]) – Spatial limits of the slit on the sky. This should be taken from the header of the hdulist, but this is not yet provided by scopesim. For the time being, these limits must be provided by the user.

  • xi_max (float [arcsec]) – Spatial limits of the slit on the sky. This should be taken from the header of the hdulist, but this is not yet provided by scopesim. For the time being, these limits must be provided by the user.

  • interps (list of interpolation functions) – If provided, there must be one for each image extension in hdulist. The functions go from pixels to the images and can be created with, e.g. RectBivariateSpline.

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:
