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?)
