Subject: | EPICS data extraction with mysql and compressed data |

Dear all, I have a question regarding recovering data archived by epics using mysql. I use a python code to automatically recover and analyse a set of data. Some of these data are constant and compressed by EPICS so when I extract them with respect to a given data stamp, it gives “nan”. The only way to get value is to have a variation. Looping the time stamps is not feasible as I can easily miss the right time stamp. Do you of of any way that could allow to directly extract constant compressed data ? Here is the code I use for the extraction :
Thank you, Best regards, Adnan Ghribi
