Justin had noticed on 25 April 2018 that West PP05TT27 had "fluctuating dark current" as seen on the GUI. 

Rosi has posted a nice summary of the situation here: drupal.star.bnl.gov/STAR/blog/rjreed/dark-current-ew1-pp5-tt27

Here, I just note a strange problem with the GUI (which you can access here by the way).  When you click on a tile, you can see at the bottom an historical "strip chart" of the dark current in the tile.  You can also "hover" your mouse over a point on the strip chart, and up will pop the numerical value of the dark current at that time.  It works nicely (try it) for all other tiles, but NOT for this fluctuating one.  See the two figures below.

Perhaps Wanbing could fix this problem?




Figure 1 - Clearly there is a discrepancy between the strip chart and the value that appears when the mouse hovers at some point on the strip chart.





Figure 2 - Here, the mouse is "hovered" at several points along the strip chart.  There is essentially no correlation between the points and the value that pops up.
