The input sources for LPV processing are the ones classified as MIRA_SR by the Classification processing (either with nTransits:2+ or with nTransits:20+ classifiers)
which meet the following selection criteria:

•

a minimum number of 12 data points in the $G$-band.
The maximum number of data points is 238.
The limit on the number of good data points led to the exclusion of several nearby and bright LPVs.

•

a minimum number of 9 data points in the ${G}_{\mathrm{RP}}$-band.

•

a colour ${G}_{\mathrm{BP}}-{G}_{\mathrm{RP}}>0.5$ mag; (colour computed as median(${G}_{\mathrm{BP}}$) - median(${G}_{\mathrm{RP}}$))

•

a correlation between the $G$-band variability and the ${G}_{\mathrm{BP}}-{G}_{\mathrm{RP}}$ colour larger than 0.5 mag.
The correlation is computed using the Spearman algorithm.

•

a variability amplitude range in $G$ larger than 0.2 mag.
The variability amplitude is quantified by the trimmed range (at 95% level).

•

a minimum Abbe value (von Neumann (1941) and von Neumann (1942)) of 0.8 on the smoothed $G$ light curve. The smoothed $G$ light curve is computed in an iterative way by merging successive pairs of observations with time difference less than 5 days.
