Field Documentation

EphemerisFilenames EphemerisData::ephiles

Names of the two files containing positions of Earth and Sun, respectively at evenly spaced times.

Definition at line 271 of file LALBarycenter.h.

INT2 EphemerisData::leap

The number of leap seconds that have been inserted into UTC between Jan 6, 1980 (= start of GPS calendar) and the current time tgps.

But its perfectly OK to approximate this by number of leap sec inserted between Jan 6, 1980 and Jan 2 of year covered by this ephemeris file; eg leap = 13 for year 2000.

Definition at line 273 of file LALBarycenter.h.

INT4 EphemerisData::nentriesE

The number of entries in Earth ephemeris table.

Definition at line 278 of file LALBarycenter.h.

INT4 EphemerisData::nentriesS

The number of entries in Sun ephemeris table.

Definition at line 279 of file LALBarycenter.h.

REAL8 EphemerisData::dtEtable

The spacing in sec between consecutive intants in Earth ephemeris table.

Definition at line 280 of file LALBarycenter.h.

REAL8 EphemerisData::dtStable

The spacing in sec between consecutive intants in Sun ephemeris table.
