ComputeSpectra¶
- class muse_origin.ComputeSpectra(orig, idx, param)[source]¶
Bases:
muse_origin.steps.Step
Compute the estimated emission line and the optimal coordinates.
For each detected line in a spatio-spectral grid, the line is estimated with the deconvolution model:
subcube = FSF*line -> line_est = subcube*fsf/(fsf^2))
Via PCA LS or denoised PCA LS Method.
- Parameters
- grid_dxy
int
Maximum spatial shift for the grid, defaults to 0.
- spectrum_size_fwhm: float
The length of the spectrum to keep around each line as a factor of the fitted line FWHM, defaults to 6.
- grid_dxy
- Returns
- self.Cat2
astropy.table.Table
Catalog of parameters of detected emission lines. Columns: ra dec lbda x0 x y0 y z0 z T_GLR profile residual flux num_line purity
- self.spectra
list
ofSpectrum
Estimated lines.
- self.Cat2
Attributes Summary
Description of the step.
Name of the function to run the step.
List of required steps (that must be run before).
Processing status (
muse_origin.Status
):Methods Summary
__call__
(*args, **kwargs)Run a step, calling its
run
method.dump
(outpath)Save the attributes that have been created by the steps, and unload them to free memory.
load
(outpath)Recreate attributes of a step, not really loading them as just the file is set, and files are loaded in memory only if needed.
run
(orig[, grid_dxy, spectrum_size_fwhm])store_cube
(name, data, **kwargs)Create a MPDAF Cube and store it as an attribute.
store_image
(name, data, **kwargs)Create a MPDAF Image and store it as an attribute.

- status¶
Processing status (

):NOTRUN: The step has not been run.
RUN: The step has been run but not saved.
DUMP: The step has been run and its outputs saved to disk.
FAILED: The step has been run but it failed.
Methods Documentation
- __call__(*args, **kwargs)¶
Run a step, calling its
run
method.This method is the one that is called from the ORIGIN object. It calls the
run
method of the step and also does a few additional things like storing the parameters, execution time and date.
- dump(outpath)¶
Save the attributes that have been created by the steps, and unload them to free memory.
- load(outpath)¶
Recreate attributes of a step, not really loading them as just the file is set, and files are loaded in memory only if needed.
- store_cube(name, data, **kwargs)¶
Create a MPDAF Cube and store it as an attribute.
- store_image(name, data, **kwargs)¶
Create a MPDAF Image and store it as an attribute.
