the accurate flux calibration of the iso instruments relies on our knowledge about the atmosphere models of stellar standard candles, but the accurate knowledge of these models in turn relies on the high-spectral-resolution observations of these stars, which precisely require iso. clearly, then, the final iso-sws calibration will result from an iterative process involving both observations of standard stars and interpretation in terms of stellar-atmosphere models. this process will benefit both to the general community interested in a good calibration and to the subcommunity interested in understanding stellar atmosphere models in detail. we propose to obtain full-resolution sws full scans of a few selected standard stars, with the purpose of assessing in detail which are the atomic and molecular features for which an improvement of the models is necessary, and then will contribute to this improvement.

Mission Description
The Infrared Space Observatory (ISO) was the worlds first true orbiting infrared observatory. Equipped with four highly-sophisticated and versatile scientific instruments, it was launched by Ariane in November 1995 and provided astronomers world-wide with a facility of unprecedented sensitivity and capabilities for a detailed exploration of the Universe at infrared wavelengths.
