The input data for filtering should be prepared in ASCII form (only Y(i) values) in a file in the computer, where you run your browser. After fulfilling this task submit your data for smoothing using the form below. You will see the graph presenting the original and smoothed data.

You may look at the file containing sample input data and see the result of processing these data (with detected outlier points).

Minimum recommended number of input data points: N = 64
Maximum allowed number of input data points: N = 8192
