mesa-users] big fix: 2258 replaces 2244; and improved eos tables

[Bill P. <pa...@ki...>]

Hi,

Sorry for the inconvenience -- 2244 slipped through our test suite in  
spite of a nasty bug in mesa/star
concerning non-solar opacities.  It is fixed (and the test suite is  
updated!) -- so please update to 2258.

Note that 2258 also has a new set of eos data, so you'll need to  
remove data/eosDT_data before installing.
(If you forget, it will remind you.)   The new eos data is actually  
quite significant if you are doing models that
enter the low T, high P range where we use the SCVH EOS.   Thanks to  
Didier Saumon, we now have access
to an extended set of values that make our interpolation much more  
accurate.   The new values do NOT
extend the valid range of the EOS; they are "off-table" values that  
are only useful because they fill out the
rectangle of data needed in order to create good bicubic splines for  
interpolation.   It is ironic but true that
data outside of the range of validity of the eos is helpful with  
interpolating the data in the part of the (logT,logP)
space that we actually want to use.  So thanks again to Didier for  
sharing this with us.  In case you
are curious, here are the new tables we are using with values for the  
high P range;  again, understand
that the extra values are not to be used directly -- they are only  
present to help creating interpolating splines.
