There IS one absoulutely correct result for refraction...the giant analog computer over our heads. And its fast. Unfortunaltely, it ONLY runs real time. I used the star link R F R O subroutine by Wallace (head of the UK Natu Alm Office. ( It reproduces the critical table in the Naut Alm exactly.) * P.T.Wallace Starlink 3 June 1997 * The routine computes the refraction for zenith distances up * to and a little beyond 90 deg using the method of Hohenkerk * and Sinclair (NAO Technical Notes 59 and 63, subsequently adopted * in the Explanatory Supplement, 1992 edition - see section 3.281). --~--~---------~--~----~------------~-------~--~----~ Navigation List archive: www.fer3.com/arc To post, email NavList@fer3.com To , email NavList-@fer3.com -~----------~----~----~----~------~----~------~--~---
