Played around with it a lot and came to some startling conclusions:

About PAR0:

• PAR0 seems very likely to be the number of hundredths of a second it takes for the repair system to restore a damaged shield.
• So if PAR0 is set to 100, it repairs a system in 1 second.
• When I set PAR0 to be 1, it resulted in my systems briefly flashing red or yellow when I was damaged, and then instantly returning to green.

About PAR1:

• PAR1 doesn't seem to do much. I tried it with values of 1, 3, 9, and 100, and couldn't really see a difference.
• There's a small possibility that it's how many systems it can repair at once. That would result in 9 and 100 looking functionally the same, since no ship I tried it on had more than 9 systems.
• Definitely PAR1 has nothing to do with actually repairing your hulls. If it did, then setting it to 100 should have been really noticeable.
