An installation guide to the PC-based time-series data-management and plotting program BOB
Thomas L. Murray · Antarctica A Keystone in a Changing World · 1990
BOB is a command-driven FORTRAN program for cleaning, plotting, and comparing time-series data from low-data-rate sensors (sampling intervals greater than or equal to one minute).It is not meant to be a complete graphics package providing publication quality graphs.It will however provide quick and easy access to large sets of time-series data (some in excess of 50,000 data points/year collected over a period of years) and produce plots containing all the essential information.The data from various parameters (tilt, strain, chemistry, earthquake counts, etc.) can be compared with previous time periods and each other.With a real-time telemetry system capable of updating data files every 10 minutes, BOB provides the environment to monitor the sensors virtually in real-time.The information made available by BOB, along with that provided by a real-time seismic data-acquisition and analysis system allows near-real-time monitoring of most currently-accepted predictors of volcanic eruptions.BOB's minimum system requirements: IBM PC XT or compatible 640 Kbytes on board RAM 10 Mbytes hard disk DOS 3.2 or greater Geograf graphics utilities, Geocomp Corp., Concord, MA QDOS II or similar software package for moving files, creating directories, word processing, etc., Gazelle Systems, Provo, UT.Math coprocessor If the user wishes to set up BOB using a low-data-rate telemetry system (Murray, 1988) and a real-time seismic amplitude system (Murray and Endo, 1989) that automatically transfers data to the computer, the following minimum system is recommended: IBM PC AT or compatible DOS 3.2 or 3.3 2 Mbytes on-board RAM -LIM 4.0 compatible 10 Mbytes hard disk Desqview multitasking software, Quarterdeck Office Systems, Santa Monica, Ca.GWBASIC or other BASIC interperter Geograf graphics utilities, Geocomp Corp., Concord, MA.QDOSII or similar software package for moving files, creating directories, word processing,
