Keyword : opacity
To specify the treatment of optical depth in the rate equations the option opacity can be invoked.
In performing the calculations of the rates the radiative decay rates are corrected for opacity using a simple escape factor calculation.
The definition of the optical depth requires the path length of the uniform plasma

explanation |
| opacity size # |
option to choose to have a fixed optical path length, measured in cm, for the entire problem. This is done by using size followed by the optical path length |
| opacity off |
option which indicates that the optical depths effects are to be ignored and the calculations are to proceed as the optically thin case. |
| opacity file |
option to invoke the use of the optical path from the history file.
In the history file the column with the optical path length is specified by the column header |
