getDateAvg()

def lsst.obs.test.makeTestRawVisitInfo.MakeTestRawVisitInfo.getDateAvg	(		self,
			md,
			exposureTime
	)

Return date at the middle of the exposure.

Parameters
----------
md : `lsst.daf.base.PropertySet`
    Image metadata.
exposureTime : `float`
    Exposure time, in sec

Returns
-------
dateAvg : `lsst.daf.base.DateTime`
    Date at middle of the exposure, or `lsst.daf.base.DateTime()`
    if the metadata item ``TAI`` is not found.

setArgDict()

def lsst.obs.test.makeTestRawVisitInfo.MakeTestRawVisitInfo.setArgDict	(		self,
			md,
			argDict
	)

Set an argument dict for VisitInfo and pop associated metadata.

Parameters
----------
md : `lsst.daf.base.PropertySet`
    Image metadata.
argDict : `dict`
    A dict of arguments for the `lsst.afw.image.VisitInfo`
    constructor. Updated by this call.

Returns
-------
visitInfo : `lsst.afw.image.VisitInfo`
    Visit information.
