vgauss, zvgauss: gaussian line profile with sigma in velocity
A simple gaussian line profile with the sigma parameter as
velocity-width in km/s. If the width is then it is treated as a
delta function. The zvgauss variant computes a redshifted gaussian.

The line is truncated at the point that the integrated flux under the line is
within a critical value of the total flux. This critical value can be
changed using xset LINECRITLEVEL. The default critical value is
