You didn't show the command that you used, but yes, it looks like they
are. The devices and seg_pe_ranges parameters for lvs show the details
you're after, eg:
# lvs -o lv_name,vg_name,seg_start,seg_size,devices,seg_pe_ranges
LV VG Start SSize Devices PE Ranges
fedora vg0 0 9.75G /dev/dm-0(0) /dev/dm-0:0-311
home vg0 0 44.44G /dev/dm-0(312) /dev/dm-0:312-1733
swap vg0 0 1.50G /dev/dm-0(1734) /dev/dm-0:1734-1781
