SLIST Format Description

SLIST is a simple ASCII time series format. Each contiguous time series segment (no gaps or overlaps) is represented with a header line followed by a sample lists. There are no restrictions on how the segments are organized into files, a file might contain a single segment or many, concatenated segments either for the same channel or many different channels.

Header lines have the general form:

TIMESERIES SourceName, # samples, # sps, Time, Format, Type, Units


with

SourceName
“Net_Sta_Loc_Chan_Qual”, no spaces, quality code optional
# samples
# sps
Sampling rate in samples per second
Time
Time of first sample in ISO YYYY-MM-DDTHH:MM:SS.FFFFFF format
Format
‘TSPAIR’ (fixed)
Type
Sample type ‘INTEGER’, ‘FLOAT’ or ‘ASCII’
Units
Units of time-series, e.g. Counts, M/S, etc., may not contain spaces

Samples are listed in 6 columns with the time-series incrementing from left to right and wrapping to the next line. The time of the first sample is the time listed in the header.

Example SLIST file:

TIMESERIES NL_HGN_00_BHZ_R, 12 samples, 40 sps, 2003-05-29T02:13:22.043400, SLIST, INTEGER, Counts
