ESM REXEL-run-matching Web-Service

The ESM REXEL-run-matching web-service searches for sets of waveforms, whose spectra, on average, match the target spectrum within a specified tolerance. Data may be filtered by matching analysis options e.g. upper/lower amplitude compatibility, upper/lower period range of compatibility, etc. A complete list of supported options and usage examples is available in the query-options webpage. Requests must use HTTP-POST method.

Feature Notes

• HTTP-POST target argument is required (the output ZIP file from ESM REXEL-target-spectrum web-service can be passed)
• HTTP-POST spectra argument is required (the output ZIP file from ESM REXEL-spectra-selection web-service can be passed)
• analysis for the three-components of records (both horizontal, X and Y and vertical, Z) is allowed only when options run-ID and three-components-flag are set to '7' and '1', respectively
• in the compatibility range between lower-period and upper-period a minimum of 3 sampled periods have to be present
• output data are provided in compressed archive (format zip) containing several ascii .txt files with Unix line endings:
  1. list of spectrum-compatible combinations for horizontal/vertical components ('COMB_OUT.TXT' or 'COMB_OUT_Z.TXT')
  2. summary file resuming the query options ('REXEL_ELABORATION_SUMMARY.TXT')
  3. in case three-components analysis is performed, the file 'SPECTRAZ_COMB.TXT' is generated, containing spectral ordinates of the vertical components
• maximum execution time is limited to 180 seconds per single request
