In playing with the GPS Anti-Spoof app free version for Android, I initially set the I.C. to -60.0'...since that corresponds to the IE of an older sexant I have access to, which cannot be adjusted any closer than 56.0' away from 0.0'.
The issue is that in trying to return the configuration to an I.C. to 0.0, I find that I cannot. Right this moment, whether I hit the + or – button, the I.C. keeps incrementing in the wrong direction.
I solved the issue by uninstalling and reinstalling the app.
Once done, and I stayed with an I.C. of 0.0 (which corresponds to the good sextant I have), I found that the Ha in the app yielded an intercept of 0.2'...or within the range of rounding errors when I did my trig calculations. So...terrific app, with one quirky problem that only crops up when you use a really quirky sextant.
Thanks for building a great app, Frank.
