The number of the sectors on a track in a D40 image

Remarks

• The track number is used as index into this array. As the tracks are based by 1, the element "0" is left out and kept as zero. Additionally, the array length is one more than the number of tracks in the image.
• The number of sectors on a track in speed zone 1 (track 18 to 24) is one more than for a D64 image
