The main function in this code - XLALBinaryPulsarDeltaT - is for calculating the time delay on a pulsar signal caused by its orbit within a binary system. It tranforms a signal from the binary system barycentre to the pulsar proper time. It is equivalent to the LALBarycenter() functions for transforming the Earth reference frame to the solar system barycentre. It copies the functions from the standard pulsar timing software TEMPO and can use the various binary system models BT, BT1P, BT2P, BTX, ELL1, DD and MSS.
Included is a function to read in a set of pulsar parameters from a standard TEMPO parameter (.par) file - XLALReadTEMPOParFile.
Also included are function to convert times given in the TT, TDB or TCB frames (given as a modified Julian Date - MJD) into a GPS time.

Functions for converting times given in Terrestrial time TT, TDB, or TCB in MJD to times in GPS - this is important for epochs given in .par files which are in TDB(MJD).
TT and GPS are different by a factor of 51.184 secs, this is just the historical factor of 32.184 secs between TT and TAI (International Atomic Time) and the other 19 seconds come from the leap seonds added between the TAI and UTC up to the point of definition of GPS time at UTC 01/01/1980.
