Station Parameter file setup

Station parameter (stapar) files contain information regarding station location, sensors, dataloggers, and recording parameters as they change with time. They are named by date (YYDDDHHMMSS.msS) where the date reflects the time of the parameter changes. An example stapar file for the Anza array. Stapar files are broken up into 4 distinct sections containing information regarding different aspects of the data. These four sections are defined below:

Site ? _SID __Latitude _Longitude _Elevation N-offset E-offset V-offset
-----------------------------------------------------------------------
Site %-4s station code
? %-1s is the station up? (Y/N)
SID %4d station ID number (usually internal to stapar files)
Latitude %9.4f station latitude (decimal)
Longitude %9.4f station longitude (decimal)
Elevation %9.4f station elevation (meters)
N-offset %7.4f station north offset from reference site (if any)
(meters)
E-offset %7.4f station east offset from reference site (if any)
(meters)
V-offset %7.4f station vertical offset from reference site (if any)
(meters)
Site Comp Type Serial Theta Phi ____Freq ____Damp ____Coil RponseFile Sens Depth
--------------------------------------------------------------------------------
Site %-4s station code
Comp %4d component name (channel number or sensor code)
Type %-4s sensor type (VEL, ACC, etc)
Serial %6d sensor serial number
Theta %5.1f sensor vertical orientation (degrees from up) 
Phi %3.1f sensor horizontal orientation (degrees from north)
Freq %8.6f natural frequency of sensor
Damp %8.6f damping coefficient of sensor
Coil %8.6f generator constant of seismometer (V/cm/s)
RponseFile %-10s reference to file containing sensor response
(poles and zeroes)
Sens %-4s 3 letter sensor code (SEED convention)
Depth %5.4f sensor depth (meters)
SID %4d station 
ID number (usually internal to stapar files)
Serial %6d datalogger serial number
DataLogger %-10s datalogger type
SampleRate %10.7f sample rate
FilterResponseFiles %-46s reference to file(s) containing filter response
(poles and zeroes, or FIR coefficients)
_SID Comp dbPreAmp __dbGain Corner Roll Counts/V HighCorner _HPR
----------------------------------------------------------------
SID %4d station ID number (usually internal to stapar files)
Comp %4d component number
dbPreAmp %8.4f gain of input amplifier (if any) (dB)
dbGain %8.4f gain of amplifier (dB)
Corner %6.4f corner frequency of AAF or sample rate decimation filters
(Hz)
Roll %4.2f frequency roll-off per octave of AAF or final FIR filters
(dB)
Counts/V %8.4f datalogger digitization constant
HighCorner %10.4f corner frequency of input low pass filter (if any) (Hz)
HPR %4.2f frequency roll-off per octave of input low pass filter
(if any) (dB)
