Field Documentation

◆ tgps

LIGOTimeGPS BarycenterInput::tgps

input GPS arrival time.

I use tgps (lower case) to remind that here the LAL structure is a field in the larger structure BarycenterInput. I use tGPS as an input structure (by itself) to LALBarycenterEarth

◆ site

LALDetector BarycenterInput::site

detector site info.

NOTE: the site.location field must be modified to give the detector location in units of seconds (i.e. divide the values normally stored in site.location by LAL_C_SI

◆ alpha

REAL8 BarycenterInput::alpha

Source right ascension in ICRS J2000 coords (radians).

Definition at line 214 of file LALBarycenter.h.

◆ delta

REAL8 BarycenterInput::delta

Source declination in ICRS J2000 coords (radians)

Definition at line 215 of file LALBarycenter.h.

◆ dInv

REAL8 BarycenterInput::dInv

1/(distance to source), in 1/sec.

This is needed to correct Roemer delay for very nearby sources; correction is about 10 microsec for source at 100 pc
