AIRINDEX
| This function is based on the formulas in Filippenko, PASP, v. 94, pp. 715-721 for the index of refraction of air. The conversion from relative humidity to vapor pressure is from the Handbook of Chemistry and Physics. |

AIRMASS
| This is should be a pretty good function for computing the air mass factor. The default is to use the cosine based formula derived by David Tholen but the older secant based formula from Hardie is still available. The zenith angle is ... |
