The name of each file is prefix .JJJ.XXX.ps where JJJ is the julian day of the start of the page and XXX is the page number. Specifies the number of traces per channel to be plotted per page. That is, to determine how many traces will be on a page, multiply this number by the number of channels plotted. The number of channels is derived from the input SEGY files. On the last page, the number of traces plotted will correspond to the amount of data remaining.
Tells psql what the resolution of the printer is, where den is in dots per inch.
Defaults to 85 dpi, which for a 5 sample per second data stream is equivalent to the resolution of a typical monitor of a Sun Workstation. Using this option will slow down the program, but not by much. Command line switch to indicate that the data is in SAC format. If the number of samples per trace is less than the resolution, data are plotted using a vertical bar between the maximum and minimum values calculated over the decimated region. There are no consistency checks performed on the data to see if the traces are from different DAS or have different sample rates.
