A few things need help about output of command ModelSegments.

Hello, gatk team thanks for your good tools. Here I have some questions about output of ModelSegments.
1. *.cr.seg file NUM_POINTS_COPY_RATIO field. It's this the same with Num_Probes in CGH result? Or this means how many bins supporting this segment? I want to plot heatmap for multiple samples result use "copynumber" package in R.
2. *.igv.seg file last field Segment_Mean is absolute value of copy number ratio(all positive number in my case.)? It seems igv accept this field as log2 ratio.
3. *.modelFinal.seg LOG2_COPY_RATIO_POSTERIOR_(10/50/90) what's those posterior(10/50/90) meaning?
