Microlensing event selection cuts for Sample A
| cut | description | ||||
|---|---|---|---|---|---|
| membership score > =0.85 | membership score cut | ||||
| abs(paczynski0_u0)< 1. | only high amplification events | ||||
| 20.< paczynski0_te < 300. | timescale should be realistic and reasonable for DR3 duration | ||||
| paczynski0_g0 < 19. | magnitude cut | ||||
| skewness < 0. | only events getting brighter over the baseline | ||||
| 1.< (medianBP − medianRP)< 4. | colour cut to remove blue outburst and very red variables | ||||
| (median < 17 and (max − min)> 0.25) | |||||
| or | |||||
| (median > 17 and (max − min)> 0.5) | amplitude cut as a function of the magnitude | ||||
| stddevG < stddevRP + 0.04 or number pointsRP < 2 | RP light curve robustness | ||||
| paczynski0_tmax − 1 * paczynski0_te > t_min | at least 1 timescale within the data | ||||
| extractor_number_points_in_event > 3 | more than 3 outlying points identified by the Extractor | ||||
| duration > 135 | distance in days between outlying points from Extractor | ||||
| max_sigma_in_event > 50 | “strength” of the event from Extractor | ||||
| abs(paczynski0_u0/paczynski0_u0_error)< 200 | only fits with robust paczynski0_u0 determination selected | ||||
| paczynski0_u0_error!=0 and paczynski0_te_error > 0 | only fits with robust paczynski0_u0 and paczynski0_te selected | ||||
| paczynski2_chi2_dof < 1.9 | goodness of the parallax fit | ||||
| abs(paczynski2_parallax_east)< 3.5 | |||||
| and abs(paczynski2_parallax_north)< 3.5 | only reasonable parallax vector selected | ||||
| (paczynski0_tmax < 6, 824.5 or paczynski0_tmax > 7, 189.5) | |||||
| and log(abbe)< 0.8 * log(−skewness)−0.6 | |||||
| or | |||||
| 6, 824.5 < =paczynski0_tmax < =7, 189.5 | |||||
| and log(abbe)< 1.2 * log(−skewness)−0.84 | skew-Abbe selection more strict for events in a period of times with more photometric outliers | ||||
