MER-1 is "Opportunity".
MER-B Launch 2003 Jul 8 , landing 2004 Feb 25.
The pre-TCM1 miss distance is 340000 km, which is probably the flyby distance of the final stage.
B.R B.T = (204197,274289) with TCA 2004 Jan 26 1623:22.
Landing at around 2S, 354E. The landing site was named Challenger Memorial Station.
Landing site is 1.9462S 354.4734E. AIAA2004-4980 quotes actual as 1.94828S 354.47417E. Diff is (0.002,0.001) deg. Radius of Mars is 3397 km, so 0.001 deg corresponds to 17 murad or 60 meters. Hence 1 km = 0.01687 deg.
MER-1 entry mass was 832 kg, 5 kg more than Spirit.
At Gusev, b=14.57 so in X, 1 km = 0.01743 deg.

A Sol is 24 hours 39 minutes 35.244 seconds
Spirit: (Sol 1 ends 2004-01-04 14:15 UTC) - = landing + 09:49 Spirit landed at 14:34 LST-A = 0426 UTC Jan 4. So 24:39 LST-A is 0426 + 10:05 = 1431 UTC Jan 4. 1415 UTC = 1434+0949 LST-A = 24:23 LST-A = EOLST - 13m. Wassup? ERT error? LT= 9min
If Sol 1 end = 14:15 ERT = 14:06 UTC, that's 24:14 LST-A.
LST-B = LST-A + 12:01:10 Oppo landed at 13:33 LST-B. 0454 UTC. Oppo: (Sol 1 ends at 2004-01-25 15:48 UTC) = 10:54 after landing = 24:27 LST-A = EOLST - 12min. LT = 11 min.
If Sol 1 end is 15:48 ERT = 1537 UTC then end is 24:16 LST-A.
Ahhh.. LST runs on a 24-hour martian day with 1 mars day = 88775.244 SI second = 86400 Mars seconds so 1 Mars second = 1.0275 Earth seconds. Thus, 9:49 Earth = 9:33 Mars and A Sol 1 ends at 14:34 + 9:33 = 24:07 ? 10:54 Earth = 10:36 Mars and B Sol 1 ends at 13:33 + 10:36 = 24:09 ? Suspect ERT. Conclude A Sol 2 starts at 1406 UTC 2004 Jan 4 and B Sol 2 starts at 1537 UTC 2004 Jan 25.
Nominal landing is at 0435 ERT and 0505 ERT (A,B).= 0426 and 0454 UTC.
JD = ( A Sol - 2 ) * 1.02749125 + 2453009.087500 = ( B Sol - 2 ) * 1.02749125 + 2453030.150694
A Sol = 2 + ( JD - 2453009.087500 ) * 0.9732443 B Sol = 2 + ( JD - 2453030.150694 ) * 0.9732443
