Code added to line 115 - line 136

First test checks if the number of "peaks" measured by the HWS code makes sense. If below 800 -- not enough return SLED beam. If above 4096 (12 bit), something's wrong.

Second test checks if HWS code time stamp is correct compared to the actual GPS time. If |dt| > 15 seconds then the code must have stopped running.
