galpy.df.diskdf.targetSurfacemassLOS¶

diskdf.targetSurfacemassLOS(d, l, log=False, deg=True)[source]¶

Evaluate the target surface mass along the line of sight given Galactic longitude and distance.

Parameters:

d (float or Quantity) – Distance along the line of sight.
l (float or Quantity) – Galactic longitude in degrees, unless deg=False.
deg (bool, optional) – If False, l is in radians. Default is True.
log (bool, optional) – If True, return the logarithm of the surface mass. Default is False.

Returns:

Surface mass times distance.

Return type:

float or Quantity
