Scientific paper

Weighting functions for velocity and temperature disturbances are computed in the case of Ca II 3933, 8498, and 8542 with the HSRA model atmosphere. Temperature W-functions are generally broader than velocity W-functions, due to coupling between lines. Subsequently, formation altitudes and transfer functions for doppler shifts and intensity fluctuations are very different. Results are plotted against frequency with a view to the derivation of wave mechanical flux from line observations.
