Andres,
I stand corrected and have confused Ho with Hs in Alan's original post. My Jupiter Dec. and GHA was a bit off as well. Your graph shows the plot nicely and if Formalhaut is omitted as Jeremy has suggested because of a late twilight horizon then we are left with two LOP's that are toward the body at 1.6' and 1.7' . This suggests a possible systematic error with the leading culprits being index error and or dip correction. Setting a star/planet on the horizon rather than splitting the star/planet with the horizon may also be adding a few tenths to the observed altitude.
