Ginan pod and mannual

[xbwcsu]

Dear Ginan team, this software provides a very good learning code for POD precision orbit determination. This is the first time for me to use this type of software, and I have several questions at present. First, after I successfully built the software, I found that the relevant documentation is a little behind. The current version is still old, and the latest one is not found on the team's official website. Ginan_Using_the_toolkit_20220318.pdf in /docs/resources is difficult to match the latest version, I would like to ask if there is the latest manual. Second: I tried to extend the multi-system orbit on the basis of the case, and found that the sys_options setting in processing_options: of the yaml configuration was only opened with poor accuracy except for GPS, and found that boxwing.yaml probably did not write other system Settings. I would like to ask where I can find the relevant parameter Settings. Finally, I am very grateful for the open source program of the Ginan team, which is very good. If it can be combined with the latest tool manual, I believe that it is a good software for beginners to learn precision orbit determination!
