    Dear Sir,
    
    
    
    In a Document on Lunar distances I found on the web, you published the 
    following example, but I was not able to find any published solution from 
    you.
    
    So runs this example :
    
    Apr 08, 2001
    
    All observations time(s) are given from the stop watch used, which is supposed 
    to be indicating a time (very) close to UT1. Observed heights have been 
    (mathematically) reduced into the very same time. As a consequence you 
    published only one single and same time for all observations.
    
    Approximate Position : N 44? / W 012?
    
    Watch time : 3h22m05s0 (same time for all observations, see above)
    All distances corrected for sextant error and index correction :
    Moon-Mars Distance : -65?11'9 (i.e. from Mars to opposite Moon limb)
    
    Moon Lower limb : 31?12'3 (once corrected for dip, i.e. equivalent to a height 
    observed exactly from Sea level with no sextant or index error as indicated 
    earlier)
    Mars height : 17?48'2 (same remarks as above)
    DID YOU PUBLISH YOUR RESULTS FOR THIS EXAMPLE ?
    Reworking your example with TT-UT = 64.0 seconds, I have obtained the following result :
    - Observed UT1 at time of Moon-Mars Sextant distance is equal to 3h21m09s4, 
    which makes watch used 55.6 seconds fast.
    DO YOU HAVE OTHER EXAMPLES FOR ME TO TRY COMPUTING ? ( I already worked on two other examples from you :
    - Apr 26, 2004 for which you published observed UT1 equal to 20h16m44s0 and,
    
    - Apr 02, 2001 for which you published observed UT1 equal to 17h40m28s0 .)
    Thanking you for your Kind Attention, and awaiting your reply,
    
    I am remaining,
    
    
    Most Sincerely Yours
