Data processing of PIROG 7 Data.  

For the data analysis I used Mathcad. A very powerful & easy to use program for mathematical calculations. What you see is what you get.

The baseline of the PIROG 7 flight was rather awkward. Below is extracts from the data processing of one individual Scan (305), with a large gap in the curve fitting [40,120].

A fourier series is defined for the baseline F( ).

The data is read from an asci file and defined as a matrix. After doing the definition
the mathematical operations are written and defined as if they were calculated by hand.

The residuals - the processed data for one individula scan.
