Parameters for smooth exponential atmosphere density model based on Jacchia-77

The data sets provided here can be used to derive the smooth exponential atmosphere density profile, fitted to the Jacchia-77 atmosphere density model. Both the static (at (T_\infty = 750, 1000, 1250K)) and variable model (for (T_\infty \in [650, 1350] K)) parameters are available. The model was derived to increase the accuracy of semi-analytically propagated orbits, in particular highly eccentric ones.
