Function Documentation

static __inline double GRBP__gbmMsgToPhiDouble (  unsigned short int  ra  )  [static]

Converts the right ascension, in arcmins, to PHI. Returns: PHI, in radians Parameters: ra  The right ascension, in arcmins

static __inline double GRBP__gbmMsgToThetaDouble (  signed short int  dec  )  [static]

Convert the declination, expressed in arcmins to theta. Returns: Theta, in radians Parameters: dec  The declination, arcmins

static __inline double GRBP__gbmMsgToTimeDouble (  unsigned int  tenths_secs, unsigned short int  two_usecs )  [static]

Converts the time as presented a GBM message to a double with units of a second. Returns: The converted time Parameters: tenths_secs  The number tenths seconds since the epoch two_usecs  The usecs part of the time since the epoch in two two microsecond units. Note that this value need only cover to .1 second (100,000 usecs), but since the unit are 2 usecs, need only go to 50,000. (Who comes up with this stuff?)
