This data set contains 190 SLC measurements studied by Roeder, K. (1994). Roeder (1994) analyzed this data and concluded that a three component normal mixture with equal variance is most suitable. Chen et al. (2012) also analyzed this data and gave a slightly better fit by a two component normal mixture with unequal variance. The data frame has 190 rows and 1 column.
