Since my search method also uses the partials that Paul does, I thought I'd compare them:
Mine (after some large number of iterations):
.587 .549 .137
.921 .290 .067
.642 .525 .131
.003 .010 .0056
Paul's
ITERATION #2
Sun altitude
0.048 = -.591 ∆φ - .553 ∆λ + .138 ∆CE
Moon altitude:
0.051 = -.909 ∆φ - .286 ∆λ + .072 ∆CE
Jupiter altitude:
0.050 = -.643 ∆φ - .525 ∆λ + .131 ∆CE
Lunar distance:
0.001 = -.003 ∆φ - .010 ∆λ - 0.0057 ∆CE
comforting agreement!
