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 

2-sec averaged absolute value amplitude counts

49.19 legacy value for analogs,else derived from simple_response attributes value is the averaged abs value of digital counts over 2-sec window equivalent to cutoff == Simple_Response.gain*1.7295e-07 when gain_units are counts/m/s

Magnitude units correction

Md Magnitude correction for the analog channels with different atten (gain) settings i.e. legacy cutoff == 49.14 abs averaged counts for 2-sec window of timeseries regardless of the analog gain. Default should be null or 0. for new digital types

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
