In the previous message I forgot to mention that last weekend I was looking through a few old issues of The Observatory. There were a couple articles in 1907 having to do with latitude, longitude, and time determination. One correspondent mentioned observations with a 3-inch transit instrument; it sounded like he was an amateur. The other article, the one about a theodolite method yielding results free from refraction error, has a fully worked real life example with accurate results. But that's one case. I can't help wondering if it was typical, or just lucky. http://adsabs.harvard.edu/cgi-bin/nph-abs_connect?ref_stems=Obs....30&jou_pick=YES&return_req=no_params&end_year=2008 This site has The Observatory online back to 1877. -- I block messages that contain attachments or HTML. --~--~---------~--~----~------------~-------~--~----~ Navigation List archive: www.fer3.com/arc To post, email NavList@fer3.com To , email NavList-@fer3.com -~----------~----~----~----~------~----~------~--~---
