    keyword=Run normalization and offline deadtime set up L-HRS

    1. NormAna class has been setup for the L-HRS to get the run
    normalization info and offline deadtime. The summary info is stored in
    summaryfiles/LNormAna.log in the onlana directory. 
    

    2. For the BigBite, the summary file name has bee modified to reflect the correct name and stored in summayfiles/BBNormaAna.log in the onlana directory.

    3. Modified the getDeadtime.C to look for file BBNormAna.log for the online display of the deadtime histogram for the bigbite.

    4. Need to create a similar macro as #3 for the L-HRS. I'll leave this for Bryan :)

    5. For both spectrometers the online and offline deadtime matches very well. It is time to maximize the data taking rate based on this info.

    L-HRS run 20172
