SofiaGyroDriftsInfo

class sofia_redux.scan.custom.sofia.info.gyro_drifts.SofiaGyroDriftsInfo

Bases: InfoBase

Initialize the SOFIA gyro drift information.

Contains information on the SOFIA gyro drifts and provides methods to correct integrations/scans.

Attributes Summary

lengths	Return the length of each drift (utc range).
log_id	Return the string log ID for the info.
n_drifts	Return the number of drifts (utc ranges) available.

Methods Summary

add_drifts()	Read the FITS header options and create drifts.
apply_configuration()	Apply the configuration to the information.
correct(integration)	Apply the gyro drift corrections to an integration.
get_drift_deltas()	Return the offsets for all drifts.
get_drift_utc_ranges()	Return the drift UTC ranges.
get_max()	Return the maximum drift.
get_rms()	Return the drift RMS.
get_table_entry(name)	Return a parameter value for the given name.
validate_time_range(scan)	Ensure the UTC time ranges for each drift are correct.
