In it was a form of the relativistiic Doppler shift equation that I have seen nowhere else. I had copied it down but a few years later it and a number of other useful but obscure formulas were lost when someone stole my briefcase and the notebook with the formulas. What this formula (or pair of formulas, it's been 20 years and things are rather fuzzy) gave was not only the frequency shift, but the angular shift for objects that were at an angle to the direction of travel. As I never got much past algebra it is somewhat impratical for me to attempt to derive the equation myself. If someone has such a formula would they please mail it to me? Thank you. -- Leonard Erickson ...!tektronix!reed!percival!bucket!leonard CIS: [70465,203] "I used to be a hacker. Now I'm a 'microcomputer specialist'. You know... I'd rather be a hacker."
