    Raw sight data from trek
    From: Doug Royer
    Date: 2005 Mar 2, 10:38 -0800

    Mark Burkes asked for some data from my Indian country trek of last year.
    Mike, here are a few session's data. Triangulated positions used for
    reductions not gps pos. Gps pos was recorded just as a check.
    You tell me what the position(s) is you get by whatever method you use to
    reduce them. We'll then compare final psitions.
    I used a palm OS based sight reduction program. There are limitations to it.
    One is that seperate temps can't be inputted for each sight in a round. The
    data you see is the data I recorded. That data was inputted into the
    position finding software with no upfront corrections. No reduction forms or
    almanac used. I took the average temp for each session. No averaging sights.
    I took 1 cut each body. If I screwed up I waited and did it again.
    Times written are local.
    
    Beware the time zones on these before you reduce! ! ! !
    
    11-02-04 1053 zt triangulated position = 32* 50.3 ' N   114* 44.6' W
    about 1/10th mile off from gps pos.
    All sights Sun L.L.
    sextant is  0.3' off arc
    temp = 80* F
    083739      hs = 55* 42.9'
    094418      hs = 73* 01.3'
    105327      hs = 82* 48.9'
