sccala.asynphot.aks_correction.aks_correction(snname, photometry_file, filter_in, filter_out, output=None, modelpath='Models', epoch_region=None, lsb=[0.0, 0.0], maxiter=10, save_plots=True, save_results=True, delimiter=',', disable_mean_fit=False, inspect_phot_interp=False)

Do a full AKS correction on input photometry. Corrects any number of input filter bands to specified output filter bands. Only works if the input photometry only consits of photometry taken by the same instrument. Using multiple instruments might lead to unexpected results.

Parameters

snnamestr

Name of the SN to be corrected. The model spectra used in the correction need to be stored under the same name in the model directory specified by the modelpath option.

photometry_filestr

Path to the input file containing the photometry data. Data should be formatted similar to the output files of the OSC.

filter_instr

Path to a text file containing the names of the intput filters which are to be used for the correction.

filter_outstr

Path to a text file containing the names of the output filters which are to be used for the correction.

outputstr

Name of the output file where the corrected photometry is stored. Default: None

modelpathstr

Path of the direcotry where the model spectra used in the correction. Should have a similar directory structure to the Data directory. Default: ‘Models’

epoch_regionlist or Tuple

Epoch range from which input photometry is considered. Data outside this range is discarded. Default: None

lsblist or Tuple

Extrapolation rules to consider spectra outside the specified epoch_range. Default: ‘[0.0, 0.0]’

maxiterint

Maximum number of iteration to adjust flux density to match observed photometry.

save_plotsbool

If True, diagnostic plots showing interpolated AKS correction values will be saved in the diagnostic directory. Default: True

save_resultsbool

If True, detailed AKS correction results will be stored in the results directory. A separate file will be stored for each filter band. Default: True

delimiterstr

Delimiter used in the model spectra. Default: ‘,’

disable_mean_fitbool

If True, mean fit will be disabled in photometry interpolation. Default: False

inspect_phot_interpbool

If True, interactive plots will be show to verify that photometry was interpolated correctly. Default: False

Returns

aks_corr_phot, aks_corr_phot_err
