The option is nowavailable to view results of filtering using user selected polygon within themodule.  For processing data, polygon is usually picked in the program thenpassed to the '<A HREF = "../7.fkfilter/fkfilt.html">fkfilt</A>' processing module from a processing script.INPUTinput parameters should be specified in the menu of this module.Data should be in DSI format.Max. Freq. is the maximum frequency to be examined in the datadx is the spacing between tracesthe 'polygone' input parameter is optional.  It allows visualization ofpolygones that have been saved previouslyOUTPUTx,y coordinates of the corners of filter polygone; give name at promptThere are buttons on the display screen for zoom, full (zooming out),menu (brings menu screen to the front), quit (exits program, prompts forname of variable in which to save picked polygon), pick (initiates pickingof a new polygone.  Pick with left mouse button, use right button to closepolygon) and clear (clears existing polygon from screen).  There are fourradio buttons that control the display.  'FK' displays the fk spectrum andallows picking, 'unfiltered' displays the unfiltered data, 'pass' displaysthe data with a pass filter applied and 'reject' does the same except thecontents of the polygone is rejected.note - requires files <A HREF = "../7.fkfilter/fkfig3.html">fkfig3</A>, <A HREF = "../7.fkfilter/fkquit.html">fkquit</A>, <A HREF = "../7.fkfilter/fkmenu.html">fkmenu</A>, pickfk, and fkfiltDSI customized VSP processing softwaredeveloped by G.
