acdc.dark_correction.Acdc

class Acdc(indir, darkcorr_outdir, x1d_outdir=None, binned=True, segment=None, hv=None, overwrite=False, exclude_airglow=False, superdark_dir=None, superdarks=None, calibrate=True)[source]

Bases: object

Perform a custom dark correction on COS/FUV data.

indir

Input directory that houses corrtags to correct.

Type:: str

darkcorr_outdir

Custom dark-corrected corrtags will be written here.

Type:: str

x1d_outdir

Custom dark-corrected x1ds will be written here.

Type:: str

binned

If True, pre-binned superdarks will be used.

Type:: Bool

corr_dict

Dictionary where each key is the segment+HV setting and each value is a list of all corrtags with that setting.

Type:: dict

custom_corrtags

List of corrtags which have had the custom dark correction applied.

Type:: list

dark_dict

Nested dictionary where each key is the segment+HV setting and each value is a dictionary where each key is the type of superdark (either ‘active’ or ‘quiescent’) and each value is the superdark name.

Type:: dict

Parameters:

indir (str) – Input directory that houses corrtags to correct.
darkcorr_outdir (str) – Custom dark-corrected corrtags will be written here.
x1d_outdir (str) – Custom dark-corrected x1ds will be written here.
binned (Bool) – If True, pre-binned superdarks will be used.
superdark_dir (str) – Location of superdarks.

Methods

`calibrate_corrtags`	Calibrate custom dark-corrected corrtags to product x1ds.
`custom_dark_correction`	Perform the custom dark correction.
`get_best_superdarks`	Sort superdarks into a dictionary based on segment and HV setting.
`sort_corrtags`	Sort corrtags into a dictionary.
`unzip_superdarks`

calibrate_corrtags()[source]

Calibrate custom dark-corrected corrtags to product x1ds.

Calibrate each custom dark-corrected corrtag using the BOXCAR extraction method in CalCOS. The TWOZONE extraction method does not work with BACKCORR=OMIT.

custom_dark_correction()[source]

Perform the custom dark correction.

For each corrtag, use the superdarks to predict the dark rate across the entire detector. Then use this predicted dark rate to perform a custom dark correction to each corrtag.

get_best_superdarks(superdarks)[source]

Sort superdarks into a dictionary based on segment and HV setting.

Returns:: dark_dict (dict) – Dictionary where each key is the segment+HV setting and each value is a list of all applicable superdarks.

sort_corrtags(corrtags)[source]

Sort corrtags into a dictionary. If specified, filter corrtags based on segment and HV setting.

Parameters:: corrtags (array-like) – All corrtags to be corrected.
Returns:: corr_dict (dict) – Dictionary where each key is the segment+HV setting and each value is a list of all corrtags with that setting.
