Robust Chauvenet Outlier Rejection

1 code implementation13 Jul 2018 M. P. Maples, D. E. Reichart, N. C. Konz, T. A. Berger, A. S. Trotter, J. R. Martin, D. A. Dutton, M. L. Paggen, R. E. Joyner, C. P. Salemi

Chauvenet rejection is one of the oldest, and simplest, ways to account for this, but, like sigma clipping, depends on the sample's mean and standard deviation, neither of which are robust quantities: Both are easily contaminated by the very outliers they are being used to reject.

We find that overall, between the late 1950s and late 2010s, Cas A faded at an average rate of $0. 670 \pm 0. 019$ %/yr in L band, consistent with Reichart & Stephens (2000).
