After finding a problem with the gas mixer a test is performed to compare drift time spectra taken with a premixed gas and with the gas mixer. The GARFIELD calculation can be found in following figure:
4 straws will be compared: straw# 1-6-9-15. Let's start with the pedestal versus time:
(left is gas system - right is premixed)
