What means some parameters in the config file

[MrCorsair3]

Hello,
Thank you for brilliant work, I read paper and now Im studing code and I have some doubt.
I have a question about params in config file.
I dont understand crealy what means: shot_num and seq_len.

I also dont understand exacly why in _image config file exist network "LGSS_image" and in other config file exist "LGSS" network, what is difference between them ?

Thank for help,
Best
