82 AUTOSTAR CCD PHOTOMETRY
Determining μ and ζ
bv
A plot of ((B – V) – (b – v)
o
) versus (B – V) has the slope
(1 – 1 / μ) and intercept ζ
bv
/ μ, from which the values for μ and
ζ
bv
can be calculated. The slope (1 – 1 / μ) has a value near zero
and can be determined more accurately than the simple slope μ.
Table E-11 lists the data and Figure E-7 shows a plot of the data.
The equations are in the form of an equation for a straight line:
((B – V) – (b – v)
o
) = (1 – 1/μ) * (B – V) + ζ
bv
/μ
