- Summary:
- I was reading a paper and I need help with the derivations of the equations for occultation timing. Where were these equations first derived?

### The Burst and Transient Source Experiment Earth Occultation Technique

https://www.semanticscholar.org/pap...hman/b4e57f91de6fec73fa680bcd7d6efbdf0de10beeIn **Appendix B**, the authors derive the equations for the occultation times. However, it appears that many steps were left out. I suspect that these equations were first derived elsewhere. Do you happen to know where? I have tried looking into the citations in the last paragraph of the **Introduction**, but to no avail (maybe I did not look carefully enough?) It might possibly be located in the Proceedings to the Gamma Ray Observatory Science Workshop...

Thanks in advance!

P.S. I am just trying my luck here {:-)
