New work

 1) wrote the script comparing MESA profile with OPAL EOS and ideal gas EOS

Problem with OPAL EOS:
 
 1) Ideal gas EOS pretty much works when comparing with MESA profile
 2) OPAL EOS agrees at very high pressure, but fails at large r and low pressure (reason unclear)
 3) uses density and internal energy as the independent variables.
 4) (CHECK THIS) pressure gives negative values

New work

 1) rewrote the script comparing MESA and OPAL
 2) OPAL EOS and ideal gas follows MESA, but ideal seems to follow better

Next step

 1) Interpolate OPAL EOS to get a more relatistic EOS, and use it to compare with MESA

New Work
 1) Looked on OPAL EOS 2005 website and there is an EOS with Z = 0.02 and X = 0!
 2) Compared OPAL EOS and MESA output. Sent an email to Luke reporting updates and asking for suggestions to next step.

== July 21th ==

Luke asked me why is OPAL EOS different from MESA output. I think it can be that the interpolation method is different
	Next time: Try interpolating in 1D, then make the <temperature, rho> or <energy, rho> data a grid, and use the grid to interpolate for temperature
