Calculate the arc (Capa) in degrees for a given Jya value.
Note: The traditional text describes find the arc by reversing the table
lookup (inverse interpolation). This function uses Math.asin for
computational precision while adhering to the R=3438 baseline.
Parameters
jyaVal: number
The Jya value (R × sin(θ))
Returns number
Angle in degrees (0° to 90° range for positive input)
