It is conventional to use a capital F for a cumulative distribution function, in contrast to the lower-case f used for probability density functions and probability mass functions.
Continuity of the distribution implies that P(X = a) = P(X = b) = 0, so the difference between "<" and "≤" ceases to be important in this context.) The function f is equal to the derivative of F almost everywhere, and it is called the probability density function of the distribution of X.
The Kolmogorov-Smirnov test is based on cumulative distribution functions and can be used to test to see whether two empirical distributions are different or whether an empirical distribution is different from an ideal distribution.

 CR105 - COMET OF VULCAN
Here, we are assuming that the distributions are Gaussian and the two methods to determine the periods involved are independent of each other.
Consider the case for determining the probability, Pr(CR105,IRAS), that the orbital period of is related to a theoretical 3:2 resonate orbital period determined using the IRAS point.
In the case of Buddha, a normal "parallel" is involved because both the Sun and Vulcan are at the same negative (southern) declination.
