Instructions for plotting drifter positions: etm 8/05 1) from pine, use "e" to estrast the messages to m1.txt then use awk '$1 ~ /02182/ && $2 ~ /52484/ && NF == 12 {print $0}' to get the headers. 2) then cut and paste from the april window with the awk output into files names l_argos_pos.txt (52484) and drft_shp.txt (52486) 3) map_argos to generate a plot of both drifter's tracks (There are 3 gtexts to add when you run this .mfile.) 4) run cvt_argos to generate 3 axis output for plotting on the underweigh ADCP plots Arguments for 52484 are: cout=cvt_argos(s2, s3, lat, lon); and 52486 are cout6=cvt_argos(s2n, s3n, lt, ln); 5) cut and append the end of output of cvt_argos into a text file (one for each float arg_cvt_82584.txt and arg_cvt_82586.txt) (which I gave to Dennis and he input into the RT program somewhere). I hope this helps! Have a great cruise! E.
