    Our esteemed friend Hanno Ix showed me how to do lunar clearance with Hv-Doniol  (with Lars modification?)  a few months ago before he unfortunately left us.

    The same Karl page 93 example.

    RBA:

    LDsd =  52 deg 23';

     Hsd  =  38 deg 40';

     hsd  =  30 deg 36'

        Lars                  with  lunar variables                       value

    Set:      PD           =      LDsd;                                        52deg 23'

                 N            =       hav ( Hsd - hsd )                         0.0049

                 P            =       hav( Hsd + hsd )                         0.3230

                 Q            =       P + N                                        0.3279  

    then   RBA          = arc hav [  (hav ( PD ) - N / (1 - Q) ]  =  64deg 12.9'
    _______________________________________________________________

     

    LDo:

    RBA   =  64deg 12.9'

      Ho    =  38deg 38.7

       ho   =   31deg 21.4'

             hav - Doniol         with lunar variables              value

    Set:         n             =        hav ( Ho - ho )                        0.0040        

                   p             =        hav ( Ho +ho )                         0.3290      

                   q             =        p + q                                      0.3330       

    then  LDo              = arc hav [ n + ( 1 - q ) * hav (RBA) =  52deg 2.55'

    I have never tried Ageton, but may do some comparisons in the next few months,if I find time.(I find semi reitirement very busy!). I shall compare calculator, Fuller slide rule, BN, Hv Doniol and probably now Ageton.

    All good fun.

    Really miss Hanno in these fascinating discussions.

    Best wishes all,

    Francis
