How to get the csv data I want?

I got a data set with a ulg file and a csv file, but I am a little curious about the source of his csv file.

I tried to use pyulog to convert the ulg file into a csv file, but among the dozens of csv files I got, I couldn’t find the attributes similar to the csv file he provided(They don’t have attributes like yawrate and pitchrate).

How are the rollrate and pitchrate parameters obtained from the ulg file?
