In reality I had a load of legs and splays in between the two commands. Several were shot with a Disto through water, to allow me to accurately render a sump. Water exaggerates the lengths, but that can be corrected with a scaling factor (refraction ignored) so my actual data looks like this: calibrate tape 0 0.92 # shot through water 4 - 2.23 97 -45 ...loads more splays... 4 5 6.52 123 -87 calibrate tape 0 # back to regular stuff 3 6 8.78 74 12 It got all the lengths wrong from that 3-6 leg onwards. _______________________________________________ Therion mailing list Therion@speleo.sk https://mailman.speleo.sk/listinfo/therion
