2280	u16 × 228	Mineral cost
2736	u16 × 228	Gas cost
3192	u16 × 228	Name, a string number; 0 for the default name

Example#

Each column is one value per unit type, so a unit type's values are spread across the section: its entry in each column is at the column's offset plus the unit type times the column's width. A Carrier (unit type 72) given 400 hit points and a new cost:

  72  00           does not use the game's own values
 516  00 90 01 00  hit points 102400 = 400 × 256
1284  96 00        shields 150
1668  04           armour 4
1968  34 08        build time 2100 frames
2424  2C 01        300 minerals
2880  C8 00        200 gas
3336  00 00        the game's own name

The first byte is what makes the rest count: while it is 1, the game uses its own values for the unit type and ignores the other columns. UNIS is laid out the same way with 100 weapons instead of 130, so every column is at the same offset except the last, the damage each upgrade adds.
