lsst.cp.pipe.utils.checkExpLengthEqual(exp1, exp2, v1=None, v2=None, raiseWithMessage=False)

Check the exposure lengths of two exposures are equal.

Parameters:

exp1 : lsst.afw.image.Exposure

First exposure to check

exp2 : lsst.afw.image.Exposure

Second exposure to check

v1 : int or str, optional

First visit of the visit pair

v2 : int or str, optional

raiseWithMessage : bool

If True, instead of returning a bool, raise a RuntimeError if exposure times are not equal, with a message about which visits mismatch if the information is available.

Raises:
