- jwst.photom.time_dependence.powerlaw_correction(midtime, t0, year1value, tsoft, alpha, bounded=False)[source]
Power-law correction to photometry value.
- Parameters:
- midtimefloat
Mid-point MJD of observation.
- t0ndarray
Reference day in MJD.
- year1valuendarray
Relative throughput 1 year after t0.
- tsoftndarray
Softening parameter for power law decline.
- alphandarray
Power law loss coefficient.
- boundedbool, optional
If
True, any correction value greater than 1 is set to 1.0.
- Returns:
- correctionndarray
Multiplicative correction values corresponding to the input parameters.
