      Correct the specification at line 1165 Table 16-3, Figure 16-3, and the schema to describe the type of both Flicker ST and Flicker ST (and the appropriate schema names) as float.

      The description should be "A measurement of [long term][short term] Rapid Voltage Change. The actual periods for measurement are defined in the measurement protocol documents."

      Also table 16-2 line 1159, change "A described in" to "As described in" and "61000+2003}" to "61000-2003"

      All,

      Below please find comments on the definition of flicker measurements. As indicated by Erich, there is no such thing as a flicker count as related in Table 16-3 Power Quality Indicators (line 1165). Rather, these are floating point dimensionless quantities interpreted roughly as a figure of merit with a value of 1.0 that value where 50% of people would notice it in an incandescent light bulb.

      It is suggested that the definitions be modified accordingly.
