Unique network identifier. This character string is the name of a seismic network 

Range: Any free-format string up to 8 characters. If available, use the two character FDSN code for the network  

Station code. This is the common code-name of a seismic observatory. Generally only three or four characters are used 

Range: Any free-format string up to 6 characters 

SEED channel name. The first character denotes the band code, the second for the instrument code and the third represents the component code 

Range: seedchan = {E | S | H | B | M | L | V | U | R} U {A | B | D | F | G | H | I | K | L | M | P | R | S | V | T | W} U {Z | N | E | A | B | C | T | R | 1 | 2 | 3 | U | V | W} Band code: Sample rate (Hz) Corner period (sec) E = extremely short period ³ 80 < 10 S = short period ³ 10 to < 80 < 10 H = high broad band ³ 80 ³ 10 B = broad band ³ 10 to < 80 ³ 10 M = mid period > 1 to < 10 L = long period ~ 1 V = very long period ~ 0.1 U = ultra long period ~ 0.01 R = extremely long period ~ 0.001 Instrument code: A = tiltmeter B = creepmeter D = pressure F = magnetometer G = gravimeter/accelerometer H = high gain seismometer I = humidity K = temperature L = low gain seismometer M = mass position seismometer P = geophone R = rainfall S = linear strainmeter V = volumetric strain T = tide meter W = wind Component code: N = north-south E = east-west T = transverse R = radial Z = vertical A, B, C = triaxial 1, 2, 3 = orthogonal components but non-traditional orientations U, V, W = optional components  

Describes the individual sites on an array station, operated by the same network operator 

Range: Any free-format string up to 2 characters long 

This attribute denotes the start date 

Range: Any valid date between January 01, 4712 BC and January 01, 4712 AD Units: YYYY/MM/DD HH24:MI:SS  

This attribute denotes the end date 

Range: Any valid date between January 01, 4712 BC and January 01, 4712 AD Units: YYYY/MM/DD HH24:MI:SS  

Channel name 

Range: Any valid channel name, which may be network-specific. Networks using SEED channel names should use the same value for channel and seedchan 

Domain for channel. This specifies what naming convention is used for the channel name (i.e. SEED, USGS, etc.) 

Range: Any free-format string up to 8 characters long 

Sample counts at which signal clips

Clip data dependent on instrumentation so should mirror Simple_Response. By default use the MAX digital counts of digitizer output for clip when clip counts unknown

Load date. Date and time that the record was created or last modified, in Oracle date datatype 

Range: Any valid date between January 01, 4712 BC and January 01, 4712 AD Units: YYYY/MM/DD HH24:MI:SS
