Rejection rates difference between Sigma Clipping and ESD

Andre Vilhena
in PixInsight
Hi,

In the videos concerning integration, the one about Sigma Clipping mentions that a pixel rejection between 1-2% is an healthy rate (my interpretation). However, the rejection rate obtained in the video about ESD is much lower - shouldn't ESD parameters be set to get the same 1-2% rejection?

TIA.

    No. ESD is a more "efficient" rejection method. You will not get the same number of values rejected- but of the things it does reject- it does a fantastic job. This means that a sigma threshold method is easier to manipulate (as I demonstrated)- but ESD is a fine algorithm.
