Function Documentation¶

double lsst::meas::modelfit::detail::phid(double z)¶

Compute univariate normal probabilities.

This function computes

\[ \frac{1}{2\pi}\int_z^{\infty}dx\;e^{-x^2/(2z^2)} \]

This is just a simple wrapper around boost::math::erfc, used to provide the particular form expected by bvnu.
