1.57 GW is from Kira's explanation of the Cardassian disruptor rifle.

Given that phasers/disruptors are described as a stream of rapid pulses as well as being visually a stream of pulses. And that they are beam weapons, and therefor can not be measured in joules alone. I used the 0.003 second recharge as the time between the release of each 4.7 MJ pulse which results in a total firepower of 1.57 GW.

DS9: "Return to Grace":

Kira: "This is a standard issue, Cardassian phase-disruptor rifle. It has a four point seven megajoule power capacity, three millisecond recharge two beam settings."

TNG: "The Mind's Eye"

Data: "Energy flow is within normal parameters, from the pre-fire chamber to the emission aperture."
LaForge: "Rapid nadion pulse, right on target. Beam control assembly, safety interlock, both checked out. Beam width intensity controls also responding correctly."



For the firepower of Dukat's freighter, I calculated it to around 8.9370 PW (2.136 Mt/s). This is based on the end of the phaser beam being the same width as in the shot against the 220 meter wide Bird of Prey, which makes the asteroid 92 meters in diameter. I plugged that into the stardestroyer.net asteroid calculator. Using 20% nickel-iron and 80% granite with 90% vaporization (based on visuals) gives 3.204 Mt. The beam duration was about 1.5 seconds for 2.136 Mt/s.

Okay, but what does the TNG "The Mind's Eye" quote have to do with the power calculations.

Going back to the energy increase for vaporization of granite, does the increase translate to a higher melt point as well? If so, then most of the rest of the calculations need to be changed accordingly.

No, it does not change the melting point. It is just a new calculation for joules per cubic meter vaporized. If you look at the melting point I used earlear it is the same as in the vaporization calculations, plus-or-minus rounding error.
