    Hello Bill,


    Happy New year 2013 !

    Congratulations on your recent Lunar Achievements.

    Just to check that I could interpret all of them correctly :

    SNO-T 8268 "Lunar2" observations were taken on Jan 05th, 2013 between 22h54m46.0s and 23h20m34.0s from N34d49'0 E173d07'0 with Height of eye = 0 ft, P=29.68"Hg and T=75F, and

    as an example Observation #7 should read :

    UT1=23h01m45.0s with Sextant observed value = 80d11'1

    I understand that before entering Frank's Calculator you corrected every such Instrument observed value by removing the value of AVERAGED Index Error (0'485) from every single Sextant value - i.e. SAME Index Correction for every single observation - no ? Accordingly, for this #7 observation, you would have entered Frank's Calculator with a Distance equal to {80d11'1 - 0'485} = 80d10'615 in addition to all other data listed here-above.

    Please be so kind as to confirm that I have correctly interpreted all your data.

    Again, your Lunar Data are quite impressive ! Thanks in advance for your Kind Attention.

    Best Regards from Mauritius Island
