摘要: We present theoretical Ca ii K-line profiles and filtergram contrasts for several recent models of solar faculae. The line vary greatly between complete partial frequency redistribution non-LTE calculations any given model. are relatively insensitive to the formation theory which simplifies calculation comparison with observations. All considered exhibit smaller than mean value observed by Mehltretter.
