PASSCAL Software

PASSCAL provides open-source software for downloading seismic data from REF TEK RT72A, RT130 and RT125, and Quanterra Q330 recorders, for quality assessment, and for conversion to other data formats for analysis and archiving at the IRIS Data Management Center.

We currently provide binaries of all PASSCAL software for Fedora Core LINUX, MacOS X, and SUN Solaris. For other operating system versions, we recommend that you compile the source code. (PQLII downloads are separate; see the PQLII page.)

Please send any bug reports to the bug tracking system or send an e-mail to passcal [at] passcal [dot] nmt [dot] edu. Be sure to include the operating system type and version number, an example command line, sample data if possible, and the version number of the problem code. Version numbers of PASSCAL code are YYYY.JJJ where YYYY and JJJ are the year and julian day of the revision.

Installation Instructions

The first step to getting PASSOFT installed on your system is to download the correct installer/package.  Packages for Mac OSX, Linux, Solaris, or Source Code are presented here.

Antelope

IRIS no longer maintains a license agreement with Boulder Real Time Technologies (BRTT) providing Antelope realtime software to IRIS member institutions. However, BRTT now provides Antelope to all educational institutions within the United States (details).  PASSCAL has a separate license specifically for the archiving of PASSCAL experiments, and we install Antelope on all field computers.  If you need Antelope for archiving your PASSCAL project, please data_group [at] passcal [dot] nmt [dot] edu (email the Data Group)

Seismic Processing Workshop (SPW) Software

 IRIS also maintains a license to fund support, maintenance, and a purchase discount for SPW through Parallel Geosciences. These services are available to IRIS member institutions. SPW seismic reflection processing system runs on Windows NT/2000 and handles SEGY, SEGD and SEG2 data formats.
