Dictionary: Hardness Ratio
Hardness Ratio. In X-ray astronomy, a hardness ratio is the equivalent of a photometric color index, and is calculated as a normalized difference of the exposure corrected counts in two energy bands A (high energy), B (low energy). A typical definition is: H R = A − B A + B, but other schemes are also used.
Confused over ore-to-plates ratio
Re: Confused over ore-to-plates ratio. by astroshak » Sun Sep 12, 2021 7:23 pm. 15/30/45 items/sec, or 900/1800/2700 items/min. Most people use items/sec, by the way, unless talking science, which is talked about per minute. For Steel Furnaces (craft speed 2) you need 24/48/72 furnaces to turn a full belt of ore into a full belt of plate.
