Sigma Clipping

Forums Variable Stars Calculation of SNR Sigma Clipping

Thanks for the reply. I had wondered how much better sigma clipping might be. Looks easy enough to implement.

I have wondered if the skewness of the sample pixels could be calculated and that used as a threshold for pixel removal – though I suspect that might be more computationally intensive than sigma clip.

I shall have a play on some data I’m working on.
