autoflag.setfreqmed - Function

2.1.1 Sets up the freq-median flagging method
Description

The freqmed method uses a median-in-frequency filter. It is very similar to timemed, except that it is based on a sliding median in frequency:

mxcbt = median{dxc′bt, where |c′- c| ≤ δ}

In all other respects this method is identical to timemed, hence we refer you you to the settimemed description for all details.

Arguments
