Dear Christoph,

That function should not be there for the reasons you mention. We never use it nor recommend anyone to use it. My suggestion is, if possible, eliminate the option in the new version of the program; or for the time being, indicate in the manual that it should not be used (as a few other ‘advanced’ features in the evaluation, for example, which are not implemented or not useful for most users).

All best,

Subject: Re: Updated MobileDOAS manual

Hi Diana and Santiago,

I've added some more information to the MobileDOAS manual in the places you had indicated. However, I myself don't understand section 3.3 in the manual - perhaps Santiago can provide some input here?

This section describes a way to change the constant exposure time during a traverse. However, doing this would definitely change the dark spectrum. When operating in 'Automatic' or 'Fixed' exposure time modes, the software just records a single dark spectrum at the beginning of the measurement using the same exposure time as the measurement. If the measurement exposure time is changed, then a new dark spectrum is needed at that new exposure time. I have no idea how to record a new dark spectrum at this new exposure time from within the MobileDOAS software.

Any ideas on this Santiago?

Thank you both for your help!

Hi Christoph,

Here is the updated MobileDOAS User Manual. I have a few comments in the documents though as I'd like to add more information about some things. Specifically, I would like more info on: 1) Fit Window, 2) Reference Files, and 3) how to take a dark measurement (just cover spectrometer?). If you'd like to read through the rest and edit/comment, please do. Once I do the finishing touches on the doc and test the 32-bit version I'll create a pre-release in GitHub and forward the link to Tamar and Santiago (and maybe Carlos?) for testing.
