Tauhid Belal Khan ,

    The easy way is now very easy.Just download EoSFit and it does it for you (It calculates all the parameters you need including their standard deviations). At this page (http://www.rossangel.com/home.htm) under software/EoSFit you will find the software, manual and the related article where you will be able to find useful and correct information about the most commonly used equations of state (thus including the Birch Murnaghan type EoS).

Cheers,

For uncorrelated errors, 

sf2 ~ sV02 (∂f/∂V0)2 + sv2 (∂f/∂V)2

sF2 ~ sP2 (∂F/∂P)2  + sf2 (∂F/∂f)2

Any standard book on error analysis on physical measurements, such as Bevington or Taylor (+ "error analysis" in the title), will cover such topics in great detail.

Hello Matteo Alvaro,

Thank you for your link.

But that software is only giving me the value of "f" & "F" not the error/stdv. Are you sure that I can get the error/stdv of those two parameter by using the EoSFit software?

Hello Alvaro,

For more information, I am using EosFit 7.0 and the data format...  "format 1 P V sigP sigV".

Tauhid Belal Khan,

Make sure that you are using the console version because at the moment you will not get there so easily with the GUI one! After you read in your dataset (that I understood contains standard deviations for both P and V data) the command you need to use in the console version is "FFCON". This will give you Ff and their e.s.d.'s. You will have the possibility to save this results in a separate output file.

If you have any further question for a quicker reply is better if you email me directly at [email protected].

Cheers,

Teo
