Description of SSI_.DAT file:
First line:
sat, iyrj, moj, idj, ihj

where:
sat = hour after beginning of the simulation (found in file startime.par)
when shock will arrive
iyrj, moj, idj, ihj = year/month/day/hour  when shock will arrive.

For each subsequent line:
PRESSU(I), PDELTA(I), PDELTAMAX(I), SSI(I), I-1, kyrj, kmoj, kdj, khj

where:

PRESSU(I) = dynamic pressure at hour (i-1) [hour 0 is at i=1]
PDELTA(I) = difference in dynamic pressure (next hour's minus this hour's)
PDELTAMAX(I) = difference in dynamic pressure [(peak pressure over the next
10 hours) minus (this hour's pressure)]
SSI(I) = shock search index for this hour ( if SSI > -1.55 or so, otherwise
= 9999.00)
i-1 =  this line's hour into the simulation
kyrj, kmoj, kdj, khj = year/mo/day/hr of this hour
