    keyword=RHRS TDC double peaks

    A second peak is seen on RHRS TDCs for both s1 and s2m. This peak has ~1% of count of main peak and it's ~100 TDC units (guess ~50ns) away from main peak. Besides, there are events below T0 on VDC timing spectrum, which should not be there.

    Both symptoms were not seen yesterday.
