Pie charts for 438 early B and 62 late B-type stars that are confirmed spectroscopically as Be stars, showing the distribution of variability types across the 8-year time domain of OGLE-III. We find 78% of the early Be stars and 58% of late Be stars to vary photometrically within the photometric precision of OGLE-III, as a result of disk modulation and/or short-term pulsations. The exact fractions are presented in Table 11 for clarity.
