[mesa-users] understand the output of mesa/star

[Jeremy Sakstein]

Hi Tingtao,

It depends what you want to visualise. If you want to watch the run proceed 
then you can use PGPLOT to visualise what is going on. If you want to plot 
the results then you need to use a seperate program to plot the data. The 
data in the columns is shown at the top of the file. Now the data that is 
output is contained in a file in /mesa/data/star_data/log_columns.list and 
you can add or remove columns to meet your needs. The best way top do this 
is to copy the file to your working directory and use the control in 
star_job "log_columns_file = '#.lis'. I use IDL to do the plots because 
there is a really good function called READCOL that lets you read long 
columns of data in and convert them to vectors but it is up to you. You 
should also have a look at TIOGA which I am only just starting to learn 
myself.

Hope this helps,

Jeremy
