The irisws-timeseries service provides access to individual channels of time series data for a specified time range. Requested segments may be up to 30 days in length and optional signal processing may be applied to return data. The time series may be returned in a variety of formats.

Output format options:

• miniSEED
• SAC zip (binary little endian)
• SAC Alpha (ASCII) [deprecated]
• SAC binary (big & little endian) [deprecated]
• Audio (WAV format)
• PNG Plot
• ASCII (data column)
• ASCII (data column, time column)
• GEOCSV (data column)
• GEOCSV (data column, time column)

Signal processing options (operations are performed in the order specified):

• high, low and band-pass filter
• remove mean value
• scaling by constant value
• deconvolution of instrument response (with frequency limits and unit conversion)
• differentiation and integration
• decimation to lower sample rates
