Vera,

You can also find the pressure in the summaries I put in

> /sphenix/data/data01/t1044-2016a/fnal/allt1044.{csv,db,root}

if you're looking for something specific, ala:

> SQLite version 3.6.20
> Enter ".help" for instructions
> Enter SQL statements terminated with a ";"

>        filename TEXT,
>        starttime TEXT,

>        events INT,
>        energy REAL,
>        h2c REAL,
