Good Time Interval: SAA

Summary

Functions:

get_gti	Return Good Time Interval (GTI)
get_gti_saa_eic	Return Good Time Interval (GTI) of SAA retrieve from EIC calibration file
get_gti_saa_in_orb	Return Good Time Interval (GTI) of SAA retrieve in FLAG_PVT of ORB_CNV FITS file

Reference

get_gti(flag_saa, orb_time)

Return Good Time Interval (GTI)

Parameters

• flag_saa – table of flag SAA -> False=out SAA, True in SAA (EXT or DEEP)

• orb_time – table of times

Returns

array of GTI

Return type

GTI type is numpy array (n,2) gti[x:0] is t_start gti[x:1] is t_stop

get_gti_saa_eic(t_att, t_orb, eic_saa_data)

Return Good Time Interval (GTI) of SAA retrieve from EIC calibration file

Parameters

• t_att –

• t_orb –

• eic_saa_data –

get_gti_saa_in_orb(t_orb, saa_type)

Return Good Time Interval (GTI) of SAA retrieve in FLAG_PVT of ORB_CNV FITS file

1. Sauvageon indicated this convention, no documentation yet available

   FLAG_PVT & 0x80 pour EXT_SAA_E*_ECLAIR FLAG_PVT & 0x40 pour DEEP_SAA_E*_ECLAIR

If no flag between [a, b] in t_orb so the GTI is [a, b+1] assume TIME_PVT in t_orb is every second
