Also, line 14 regulator has been changed for a brand new one. - Conclusion: unclear. Line 14 std dev is better than previously, but still not really great, and some evidence of zig zag again. - Meanwhile, really not sure what's up with line 9! I had redone the teflon tape after the awful 200911a results, to no avail. - Figured out line 9 (and to lesser extent line 10) issue! Very bad CO2 variability is impacting on O2! So no problem with the VUV!
