or *Cn φ1 ... φk
Table 5-62. Cosine Card
Variable
Description
= tally number.
n
= upper cosine limit of the ith angular bin for surface current
Ci
tally n.
C1 > −1.
Ck = 1.
= upper angular limit expressed in degrees
φk
φ1 < 180 φk=0
Default:
If the Cn card is absent, there will be one bin over all angles unless this
default has been changed by a C0 card.
Use:
Tally type 1 and 2. Required if CMn card is used. Consider FQn card.
C1−.866
Example:
−.5 0

or *C1 150 120 90 60 30 0
This will tally currents within the angular limits (1) 180o to 150o, (2) 150o to 120o, (3) 120o
to 90o, (4) 90o to 60o, (5) 60o to 30o, and (6) 30o to 0o with respect to the positive normal.
No total will be provided.
