If you can find it, this is very useful: Tablitsi Refraktsii Pulkovskoii Observatorii 5th Edn (1985). With a nice preface in English. Boris Garfinkel, Astronomical Refraction in a Polytropic Atmosphere, probably would give you what you want if you don't need extreme accuracy. Plenty on horizontal refraction. Astronomical Journal, 72, p 235, 1967. He gives references to earlier work which might be useful such as his 1944 paper which I don't have here. I believe the Astronomy Abstracts Service has all the older AJs available on line now. -- Mike Dworetsky, Department of Physics & Astronomy, University College London Gower Street, London WC1E 6BT UK email: mmd@star.ucl.ac.uk
