It is just the Standard Deviation function in Excel of all of the check 
star measurements for the ~ 7 hour run of the time series. In this 
particular case - the check star measurements in the V filter were: 
13.165, 13.16, 13.168, 13.167, 13.173, 13.171, 13.172, 13.175, 13.169, 
13.167, 13.178, 13.172, 13.172, 13.169, 13.177, 13.174, 13.178, 13.166, 
13.17. 13.166, 13.173, 13.17, 13.175, 13.176, 13.166, 13.173. The 
standard deviation of these is: 0.0045.
