get_pointing_mask

sofia_redux.instruments.fifi_ls.pointing_discard.get_pointing_mask(primehead, pointing_threshold, grating_idx, dt_ramp, dt_grating, df_pointing_error)

Create a boolean mask to set ramp values to NaN if the pointing at the ramp time is below the defined threshold.

Parameters:

primeheadastropy.io.fits.Header

Primary header of the loaded FITS file.

pointing_thresholdastropy.io.fits.Header

Absolute threshold of the pointing error in arcsec. The slopes of ramps with a pointing error greater than the define threshold are set to NaN.

grating_idxint

Index of the grating position.

dt_rampfloat

Duration of one ramp in seconds.

dt_gratingfloat

Duration of one grating position in seconds.

df_pointing_errorpandas.DataFrame

Dataframe listing the pointing errors at a given time.

Returns:

pointing_maskpandas.Series

Boolean mask used to discard ramps with bad pointing.
