tests.run_200x200_pixel_regions¶

Similar to legacypipe/py/test/runbrick_test.py, this runs and analyzes the output of legacypipe running on 200x200 pixels regions that obiwan has injected simulated sources intoself.

Functions

class tests.run_200x200_pixel_regions.Tolerances[source]¶

Tolerances on Tractor measured mags and test_flux_shape_measurements

Parameters:

survey – decals, bass_mzls obj – star,elg bands – grz, z dict (tolerance) – mw_transmission_input_minus_measured: obiwan looks up mw_trans before injecting, it should agree with tractor’s at that ra,dec mag_psql_minus_input_corrected_for_ext: in AB mag, ext added when inject, so compare what have in db to what injected w/out ext mag_input_minus_measured: in AB mag rhalf_input_minus_measured: arcsec that rhalf measurement can be off by

static bass_mzls(obj=None, bands=None)[source]¶

Returns dict of Tolerances

Parameters:	bands – ‘grz’ obj – either ‘elg’ or ‘star’

static decals(obj=None, bands=None)[source]¶

Returns dict of Tolerances

Parameters:	bands – either ‘grz’ or ‘z’ obj – either ‘elg’ or ‘star’

class tests.run_200x200_pixel_regions.analysis_setup(**kw)[source]¶

Loads the outputs from run_kenobi_main().run() and measurement tolerances

Parameters:	kwargs – the same inputs to run_kenobi_main

same as run_kenobi_main

tol¶

tolerance dict for flux, rhalf, etc.

load_outputs()[source]¶

Loads every output we could possibly need to evaluate a test

simcat, obitractor

jpg_coadds¶

fits_coadds¶

run()¶

Add the sources and run legacypipe

Parameters:	no_cleanup – don’t run cleanup step

tests.run_200x200_pixel_regions.at_most_N_is_false(bool_array, N=1)[source]¶

Returns True if bool_array has at most N elements that are False

Example, all(bool_array) is equivalent to at_most_N_is_false(bool_array,N=0)

Parameters:	N – the number of false elements allowed

class tests.run_200x200_pixel_regions.run_kenobi_main(survey=None, dataset=None, bands='grz', obj='elg', rowstart=0, add_noise=False, all_blobs=False, on_edge=False, early_coadds=False, checkpoint=False, skip_ccd_cuts=False, no_cleanup=False, stage=None)[source]¶

Runs main() in kenobi.py, which runs legacypipe

Works for either DECaLS or MzLS/BASS. Use setup_testcase() on the result

Parameters:

survey – decals or bass_mzls dataset – string, ‘DR3’, ‘DR5’, bands – ‘grz’,’z’ obj – ‘elg’,’star’ rowstart – default is 0 because reads randoms table from 1st row add_noise – to add Poisson noise to simulated galaxy profiles all_blobs – to fit models to all blobs, not just the blobs containing sims on_edge – to add randoms at edge of region, not well within the boundaries early_coadds – creates coadds and stops. useful for ML training/test samples checkpoint – whether to save model fitting (fitblobs) checkpoints True to use all ccds in the survey-ccds fits tables (skip_ccd_cuts=) – no_cleanup – at the end of running, obiwan reorganzes outputs, True means don’t do this stage – runbrick.py stages, default is None which runs everything

run()[source]¶

Add the sources and run legacypipe

Parameters:	no_cleanup – don’t run cleanup step

class tests.run_200x200_pixel_regions.run_kenobi_main_cosmos(survey=None)[source]¶

Supports subsets 60-69

class tests.run_200x200_pixel_regions.test_detected_simulated_and_real_sources(**kw)[source]¶

get_index_of_real_galaxy_at_center()[source]¶

There is a real galaxy at center, which tractor cat index is it?
