We are pleased to announce the updated software tools for seismology research with the release of JEvalResp and JPlotResp Version 1.51 (Instrumental Software Technologies, Inc.).

JEvalResp

JEvalResp is a Java version of the evalresp program and, like the original, it is designed to evaluate the response information from ASCII RESP files generated by rdseed (v4.1 and above). JEvalResp is also capable of fetching and processing responses from FISSURES servers. The program searches for one or more responses that match a user-specified station (or set of stations), channel (or set of channels), network and date/time value. The output of the responses is then calculated for a user-specified set of frequencies, resulting in a list of amplitude/phase or complex-spectra values (written to output files).

JEvalResp is available for download from the DHI Clients page

JPlotResp

JPlotResp is a graphically-oriented Java program for processing and plotting the response information from ASCII “RESP” files generated by rdseed (V4.1 and above). JPlotResp is also capable of fetching and processing responses from FISSURES servers. The program searches for one or more responses that match a user-specified station (or set of stations), channel (or set of channels), network and date/time value. The output of the responses is then calculated for a user-specified set of frequencies, resulting in a list of amplitude/phase values that may be written to files or plotted. Lists of complex-spectra values may also be written to output files.

JPlotResp makes direct use of functions within JEvalResp to fetch and process response data. For more details, see the JEvalResp Manual.
