The data was taken at/under 1 atm(@psi). `Under` sounds better to me. Many thanks Offroad

If the measurement was taken "at" 1 atm (whatever that means) then it's exactly "1". If it's "under" 1atm, then it's below 1 atm (so 0.99999 atm or lower).

'Atm' is short for 'atmosphere', unit of pressure and equivalent to ~ 14.7 psi. Very much appreciated. Offroad
