ComputePurityThreshold
(orig, idx, param)[source]¶ Bases:
muse_origin.Step
Find the threshold for a given purity.
- Parameters
- purity
float
Purity to automatically compute the threshold.
- purity_std
float
Purity to automatically compute the threshold on the cube_std. If None, previous purity is used.
- threshlist
list
List of thresholds to compute the purity. If not provided it is computed from the data with 50 values between 1.1*median and the max value.
- pfasegfinal
float
PFA for the segmentation based on the maxmap, defaults to 1e-5.
- bins
str
Method for computing bins for the maxmap segmap (see
numpy.histogram_bin_edges
). Defaults to ‘fd’.
- purity
- Returns
- self.threshold_correl
float
Estimated threshold used to detect on the correl, defaults to 0.9.
- self.threshold_std
float
Estimated threshold used to detect complementary lines on std cube.
- self.segmap_purity
Image
Combines self.segmap_merged and a segmentation on the maxmap.
- self.Pval
astropy.table.Table
Table with the purity results for each threshold: - Pval_r : The purity function - Tval_r : index value to plot - Det_m : Number of detections (-DATA) - Det_M : Number of detections (+DATA)
- self.Pval_comp
astropy.table.Table
Table with the purity results on cube_std, same columns as Pval.
- self.threshold_correl
Attributes Summary
Processing status (
muse_origin.Status
):Methods Summary
__call__
(self, \*args, \*\*kwargs)Run a step, calling its
run
method.dump
(self, outpath)Save the attributes that have been created by the steps, and unload them to free memory.
load
(self, 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
(self, orig[, purity, purity_std, …])store_cube
(self, name, data, \*\*kwargs)Create a MPDAF Cube and store it as an attribute.
store_image
(self, name, data, \*\*kwargs)Create a MPDAF Image and store it as an attribute.

status
¶ Processing status (

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__
(self, *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
(self, outpath)¶ Save the attributes that have been created by the steps, and unload them to free memory.
-
load
(self, 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
(self, orig, purity=0.9, purity_std=None, threshlist=None, pfasegfinal=1e-05, bins='fd')[source]¶
-
store_cube
(self, name, data, **kwargs)¶ Create a MPDAF Cube and store it as an attribute.
-
store_image
(self, name, data, **kwargs)¶ Create a MPDAF Image and store it as an attribute.
