How to get the cross slope value at a station in Python?

Hi,
I’m trying to get cross slope value of an alignment at an individual station via a Python script, but I can’t understand what I should write as the second parameter (“A” is my alignment).

A.InternalDBObject.GetCrossSlopeAtStation(4000, ???, 0)

I know, that the middle parameter should be SuperelevationCrossSegmentType, but I don’t know hot to reference to it’s members for example LeftOutLaneCrossSlope.
