Samtools stats output "reads mapped and paired"

Hi,

What does "reads mapped and paired" refer to in Samtools stats output? I can't find anything in the manual or in any literature.

Thank you

Thank you! However, I understand paired-end sequencing/reads and the reads mapped output, but I don't understand what the output for "reads mapped and paired" is. For example:

sequences: 669518   
reads mapped: 568365
reads mapped and paired: 494728 # paired-end technology bit set + both mates mapped
reads paired: 669518

I understand that 568365 out of 669518 of my reads mapped, but what does the number from "reads mapped and paired" stem from?
