    Linda, I will make a deal with you :  you tell me how you concluded  51S in the Frank Reed riddle about the ISS and I'll tell you everything about  the PCastrolabe.
    Couldn't it be something other than 51 S. You had to figure out that it was night time at the ISS ?

    Dr Reed mentionned that Dip = semi-diameter at very high height of eye.
