Gate errors from an old job in a Rigetti device, from results.json

I am working with a copy of my s3 bucket in my local pc. Some of my files are results coming from experiments done in Rigetti for which I would like to do a post-processing analysis. I can see that the data, e.g. the counts, are essentially saved in the file results.json. From this file, is it possible to retrieve the gate errors that the device had at the time of running the jobs?
