In an earlier post I claimed that the IC parameter in the anti-spoof app was applied incorrectly. Yesterday was what I calIled a calibration day - I took lots of sights and compared them with the app. I also measured the sextant IE many times by the on/off method. While processing the results I had a minties moment.  - the purpose of the IC parameter is not to apply a correction - it is to apply an ERROR.
