    Re: Latitude and longitude around noon

    Robin, you wrote "and with d = +0.1 per hour the peak occurs 15.4s later than local noon".

    Obviously you meant d = +1´per hour, and in 15.4s that influence the altitude by a quarter of an arc-second. Can you really extract those fifteen seconds of time from the raw data given by Frank, without knowing the longitude à priori? Aren't you pulling more information out of the data than that data contain?
