A check on the current OIG elsets of the these three decayers:
Cosmos 1043      5.0  1.5  0.0  5.4 v            193 x 187 km
1 11055U 78094A   98057.08454397  .02454231 -92862-6  50956-3 0  5437

TRMM H2 r2      13.5  2.5  0.0  4.2 v            221 x 182 km

Irid 42 CZ plat 10.0  3.0  0.0  3.0 d            226 x 163 km
1 25080U 97077D   98057.07434543  .03390126 -15693-5  58456-3 0  1711

These show Cosmos 1043 running 0.7 seconds early on the "9540" I posted
earlier in this thread, TRMM H2 r as 8 seconds early and the Iridium 42 
CZ-2C platform as 8 seconds late.

A new evolution for the final revs of the H2 is:
TRMM H2 r2      13.5  2.5  0.0  4.2 v            175 x 156 km
1 25066U 97074D   98057.29193189  .30404915  61868+0  19679-2 0 91435
2 25066  35.0361 151.9944 0015072 242.5537 117.2929 16.40098856 14277
TRMM H2 r2      13.5  2.5  0.0  4.2 v            160 x 146 km

With decay on this orbit.
