  • View QMS data, TM markers, and housekeeping data
  • Dead time correction
  • Background subtraction
  • Find the average ratio between two masses
  • Calculate mixing ratios for the major gases of the Martian atmosphere
  • Calculate average mass specs
  • TUNA (TUNing Analysis) package - fit a peak to each mass in a mass spec of fractional data, to look at the peak center shifts over time
  • Combine unit and fractional scan data into a "megatrace"
