Function adas.continuo

Calculates continuum emission at a requested wavelength and temperature for any ionisation stage of an arbitrary element.

Parameters

wave : float

requested wavelength (Angstrom). Can be an array.

tev : float

requested electron temperature (eV). Can be an array.

iz0 : int

atomic number of element.

iz1 : int

recombining ionisation stage.

Returns

contff : float

free-free emissivity (ph cm3 s-1 A-1) dimensioned by wave, tev

contin : float

total (free-free + free-bound) emissivity (ph cm3 s-1 A-1) dimensioned by wave, tev

Notes

The ionization stage is identified by iz1 the recombining charge state so iz1=1 for Z+ recombining to the neutral Z0.

If wave and/or tev are scalars the dimension of the returned quantities is adjusted appropriately.
