prbroad_width

PURPOSE ^

PRBROAD_WIDTH Pressure broadening line shape width

SYNOPSIS ^

function dp = prbroad_width(ga,n,t0,p,t)

DESCRIPTION ^

 PRBROAD_WIDTH   Pressure broadening line shape width

    The pressure broadening width is calculated as:

       dp = ga * p * (t0/t)^n

    The full width at half maximum (FWHM) is 2*dp
 
    The constants ga, n and t0 must be scalars, while p and t can be vectors
    or matrices (but then with matching size).

 FORMAT   dp = prbroad_width(ga,n,t0,p,t)
        
 OUT   dd   Pressure broadened width [Hz]
 IN    ga   Broadening parameter [Hz/Pa]
       n    Temperature exponent [-]
       t0   Reference temperature [K]
       p    Pressure [Pa].
       t    Temperature [K].
