    "abstract": "The theory of summation of electromagnetic line transitions is used to\ntabulate the Taylor expansion of the refractive index of humid air over the\nbasic independent parameters (temperature, pressure, humidity, wavelength) in\nfive separate infrared regions from the H to the Q band at a fixed percentage\nof Carbon Dioxide. These are least-squares fits to raw, highly resolved spectra\nfor a set of temperatures from 10 to 25 C, a set of pressures from 500 to 1023\nhPa, and a set of relative humidities from 5 to 60%. These choices reflect the\nprospective application to characterize ambient air at mountain altitudes of\nastronomical telescopes.",
