The energy balance in coronal holes and average quiet-sun regions

摘要: In this paper we construct emission measure curves for average coronal hole and quiet-Sun spectra taken during the Skylab mission with Harvard College Observatory spectroheliometer. These are then used to discuss implications energy balance in each region. We find that spectrum shows a smaller slope distribution, consistent expected expect effects of outflows. Models constant cross section loops radiative losses balanced by divergence thermal conduction flux predict an rise between 10/sup 5/ K 6/ K, observations, but not cell center or network distributions.
