    Fred did send recently these refraction values for Frank:

    I tried to find them on the USNO site and with the help of
    Google...unfortunately without luck. May I therefore ask someone in the
    list - may be you Fred? - to what atmospheric (standard) conditions
    (temperature and air pressure) they refer to?
    
    Thank you.
    Marcel
