```I am calculating thermal properties using example "example_EOS" (thermo program). I get out put but I can not understand the abbrevation "bs.d". Whereas some abbrevations (according to me)
**vol.d ==> P vs. V at various temperatures
**alpha.d ==> Thermal Exancivity Vs T
**bt.d ==> Bulk modulus vs T at various pressures
** Cp.d ==> Cp vs T at various Pressures
** Cv.d ==> Cv vs T at various pressures
** ga.d ==> Thermal gruension Parameter
** stp.d ==> Entrop vs T at various pressures
**AM I RIGHT **
Also tell me what is 4th term in weight (input and input_QHA present in QHA directry of thermo program)
