How can I get VCD?

Good afternoon

I’m university students and I’m doing my thesis using a miniDOAS. So I would like to improve my understanding about QDOAS , because I can get SCD graph,but , i want to get more accurate results .

Thanks a lot

Last Friday we released several new use cases on the toolbox/avl website.
Among this is a use case on running qdoas and an amf tool to convert SCD into VCD.
I would suggest to look there first. And if you then have any questions, feel free to post them here on the forum.
