EWDB_ChanTCTFStruct

Type:

struct _EWDB_ChanTCTFStruct

Description:

Structure for storing the Poles/Zeroes transfer function for a channel/time range, including gain and samplerate.

Note:

Field	Type	Description
idChanT	EWDBid	DB ID of the channel validity range(ChanT) for which the associated transform function is valid.
dGain	double	Scalar gain of the channel for the ChanT.
dSampRate	double	Digital sample rate of the waveforms exiting the channel for the ChanT.
tfsFunc	EWDB_TransformFunctionStruct	Poles and Zeroes transform function for the channel time interval.

EWDB_PZNum

Type:

struct _EWDB_PZNum

Description:

Describes a Pole/Zero as a complex number.

Note:

Field	Type	Description
dReal	double	Real portion of this number.
dImag	double	Imaginary portion of this number.

EWDB_StationStruct

Type:

struct _EWDB_StationStruct

Description:

Structure that provides information on seismic station components. Specifically it describes the name, location, and orientation of the sensor component for a channel. ComponentStruct would have been a better name than StationStruct since there may be multiple components at a Site/Station, and each component may have a different location/orientation.

Note:

Field	Type	Description
idChan	EWDBid	The Database ID of the Channel.
idComp	EWDBid	The Database ID of the Component.
Sta	char[10]	The Station code of the SCNL for the Component.
Comp	char[10]	The Channel/Component code of the SCNL for the Component.
Net	char[10]	The Network code of the SCNL for the Component.
Loc	char[10]	The Location code of the SCNL for the Component.
Lat	float	The lattitude of the Component. Expressed in Degrees.
Lon	float	The longitude of the Component. Expressed in Degrees.
Elev	float	The elevation of the Component above sea level. Expressed in meters.
Azm	float	The horizontal orientation of the Component. Expressed in degrees clockwise of North.
Dip	float	The vertical orientation of the Component. Expressed in degrees below horizontal.

EWDB_TransformFunctionStruct

Type:

struct _EWDB_TransformFunctionStruct

Description:

Structure for describing Poles and Zeros based transform/transfer functions.

Note:

Field	Type	Description
idCookedTF	EWDBid	DB ID of the transfer function.
szCookedTFDesc	char[50]	Function name or description.
iNumPoles	int	Number of Poles in the function.
iNumZeroes	int	Number of Zeroes in the function.
Poles	EWDB_PZNum [EWDB_MAX_POLES_OR_ZEROES]	Poles of the function.
Zeroes	EWDB_PZNum [EWDB_MAX_POLES_OR_ZEROES]	Zeroes of the function.
