Checks whether the ShortTermIlluminationStability attribute is present.
According to ISO 21073:2019, Illumination Stability is defined as the percentage deviation of Minimum and Maximum Illumination Power from the Average Power during the time interval considered. Specifically, SATB [%] = 100x {1-[(Pmax-Pmin)/Pmax+Pmin]}, where Pmax is the maximum laser power recorded during the time interval; and Pmin is the minimum laser power recorded during the time interval. This field records the Short Term Illumination Stability recorded during this Calibration Procedure by measuring Illumination Power every second for a time interval of 5 min of continuous illumination.
