The temperature corners, one .option TEMP per .lib.

Corner Temperature
Tt 27 °C, typical
Tm 42.4 °C
Tl −40 °C
Tnh 85 °C
Tah 105 °C
Th 125 °C

Tl and Th are the pair used by the slow, fast and etc targets of the cell_spice Makefile. Tnh and Tah are there for parts qualified to a narrower range than 125 °C.

Note that Tm is not in the middle of anything: it is the temperature a die tends to sit at, useful when a measurement is being matched.
