def synthesize_components(components, zcomp=None, vbuff=0 * u.km / u.s):
"""Synthesize a list of components into one
Requires consistent RA/DEC, Zion, Ej, (A; future)
Is agnostic about z+vlim
Melds column densities
Melds velocities with a small buffer (10 km/s)
Note: Could make this a way to instantiate AbsComponent
Parameters
----------
components : list
list of AbsComponent objects
zcomp : float, optional
Input z to reference the synthesized component
If not input, the mean of the input components is used
vbuff : Quantity, optional
Buffer for synthesizing velocities. Deals with round off, c, etc.
