In the event that 0 is a valid spw for cont.dat, there is a bug in the cont.dat matching that will lead to the code thinking it cant match and will not flag anything (and subsequently breaks for some reason). This PR fixes that by setting the "not found" spw to -1, which should never be a valid spw.
