We call this EM(Map) because of the source of this map file along with the extension ".map" of the sample files. Again we found no "formal" name nor do we know what equipment (likely a prober) produced this output.
Based on examining the data we believe: .=NULL, 0=FAIL, 1=PASS, R=REFERENCE

Notice that there is no stepping information or wafer diameter information in this format. Such data will have to be obtained separately and can be entered into WaferMap Convert's dialog to produce a more useful output map file.
The Unisem map format is so close to EM that we were able to use the same parser. So either format works and they share a common product ID.
