You don't want object 1, only object 0.
Hmm, math, ouch. So nb_sectors include sector_num? What I mean is
If [start, end] mean a range of

The first sector is included in nb_sectors. Mathematically the range
is defined as [sector_num, sector_num + nb_sectors). Notice the
half-open interval, sector_num + nb_sectors is excluded. The last
included sector is sector_num + nb_sectors -
