Phaser settings for the mid 25th century type II phaser
These may be different than those listed in the Star Trek: The Next Generation Technical Manual (on purpose)

Mid 25th Century Type-2 phasers have sixteen power settings:

STUNS
1. Light Stun - causes central nervous system impairment on humanoids, unconsciousness for up to 5 minutes. Long exposure by several shots causes reversible neural damage.
2. Medium Stun - causes unconsciousness from 5 to 15 minutes. Long exposure causes irreversible neural damage, along with damage to epithelial tissue.
3. Heavy Stun - causes unconsciousness from 15 to 60 minutes depending on the level of biological resistance. Significantly heats up metals.
THERMAL
4. Light Thermal Effects - causes extensive neural damage to humanoids and skin burns limited to the outer layers. Causes metals to retain heat when applied for over five seconds.
5. Medium Thermal Effects - causes severe outer layer skin burns. Can penetrate simple personal force fields after five seconds of application.
6. Heavy Thermal Effects - penetrates organic and structural materials. The thermal damage level decreases from this level onward.
DISRUPTION
7. Disruption Effects - due to widespread disruption effects, kills humanoids.
8. Disruption Effects - causes a cascade disruption that vaporizes humanoid organisms. Any unprotected material can be penetrated.
9. Disruption Effects - causes medium alloys and structural materials, over a meter thick, to exhibit energy rebound prior to vaporization.
DISRUPTION EFFECTS
10. Disruption Effects - causes heavy alloys and structural materials to absorb or rebound energy. There is a 0.55 second delay before the material vaporizes.
11. Disruption Effects - causes ultra-dense alloys and structural materials to absorb or rebound energy before vaporization. There is a 0.2 second delay before the material vaporizes. Approximately 10 cubic meters of rock are disintegrated per shot.
12. Disruption Effects - causes ultra-dense alloys and structural materials to absorb or rebound energy before vaporization. There is a 0.1 second delay before the material vaporizes. Approximately 60 cubic meters of rock are disintegrated per shot.
EXPLOSIVE DISRUPTION EFFECTS
13. Explosive/Disruption Effects - causes shielded matter to exhibit minor vibrational heating effects. Approximately 100 cubic meters of rock are disintegrated per shot.
14. Explosive/Disruption Effects - causes shielded matter to exhibit medium vibrational heating effects. Approximately 195 cubic meters of rock are disintegrated per shot.
15. Explosive/Disruption Effects - causes shielded matter to exhibit major vibrational heating effects. Approximately 450 cubic meters of rock are disintegrated per shot.
EXTREME EXPLOSIVE DISRUPTION EFFECTS
16. Extreme Explosive/Disruption Effects - causes shielded matter to exhibit light mechanical fracturing damage. Approximately 785 cubic meters of rock are disintegrated per shot.

Mid 25th Century Type-2 phasers have six width settings:

WIDTHS
1. Very Narrow – beam is 0.5 centimeters in diameter
2. Narrow - beam is 1 centimeter in diameter
3. Standard - beam is 5 centimeters in diameter
4. Medium - beam is 15 centimeters in diameter
5. Wide - beam is 75 centimeters in diameter
6. Full Spread - beam is 300 centimeters in diameter
