1-6 A6 ROCK4 - Requests application of the
ROCK4 or ROCK42 solar radiation model. [2]
9-10 I1 Newer thermal model = 0 0
Older thermal model = 1
25-44 D20.8 Satellite ID
45-59 D15.3 Satellite ID
60-72 D13.1 Satellite ID
73-80 D8.2 Satellite ID
NOTES : [1] If no satellite ID's are specified, card applies to all satellites
in run.
[2] The user may request application of this solar radiation model
for up to four satellites on one card (A maximum of 30 satellites
can be requested).
3 The new version of the rock4 solar radiation model came from
a paper given by H.F.Fliegel and T.E.Gallini at the AGU
30May91 where for BLOCK I satellites X and Z are as follows
X=-4.55SIN(B)+.08SIN(2B+.9)-.06COS(4B+.08)+.08
Z=-4.54COS(B)+.20SIN(2B-.3)-.03SIN(4B)
For BLOCK II satellites, X and Z are
X=-8.96SIN(B)+.16SIN(3B)+.10SIN(5B)-.07SIN(7B)
Z=-8.43COS(B)
[4] This card is used in conjunction with SOLRD card.
IF CARD OMITTED: ROCK4 or ROCK42 models will not be applied.
