New features include:
- wavelength binning (detla_v) - Line bin width can be made as narrow as desired.
- gaussian line profiles (dprof='g') - In addition to powerlaw (dprof='p') and exponential (dprof='e') radial distributions of line optical depth, a gaussian distribution is now available. This eliminates the need to use a discontinuous line optical depth distribution when detaching a line from the photosphere. When using dprof, note that declaring a particular distribution will tell SYNOW to ignore irrelevant parameters for that species (i.e. if dprof='g', then SYNOW will ignore pwrlawin, vmine, vmaxe, and ve).
- vmaxg - sets the velocity for the gaussian profiles.
- sigma_v - standard deviation of gaussian profiles. Typical values range from 1 to 3.
- When using power law distributions it no longer is necessary to use the same power law index for all ions.
- When two or more line optical depth distributions that overlap in velocity are used for an ion, the optical depths are now simply added.
