Limits

HotShot is designed to run on any PC under W95 or later.

Most of the processing limits are variable - memory being split according to the flow's complexity. Some are fixed. Here are a few examples:

  • shots per line
    		• marine - no limit; land - 5000
  • channels per shot
    		• marine - no limit; land - 2000
  • sort keys
    		• any number of header names
  • sort fold
    		• no limit
  • trace length
    		• no limit
  • sampling interval
    		• any (floating-point) value
  • v-t pairs per velocity function
    		• 40
  • velocity functions per line
    		• no limit
  • decon operators per function
    		• 5
  • decon functions per line
    		• no limit
  • filters per function
    		• 10
  • filter functions per line
    		• no limit
  • processing steps per flow
    		• 200

    Traces are processed and stored as 32-bit f.p.
    Trace headers are processed and stored as 64-bit f.p. (which gives 15 digit accuracy)

    Seismic input files may, in practice, be of any size (there's no 2Gb limit).
