Hello everyone.
I'm currently working on NS mass relations and trying to plot a curve with predicted masses-radii and observations on NS.
There are some free data at this website: http://xtreme.as.arizona.edu/NeutronStars/index.php/neutron-star-radii/ . I downloaded the .tar file and tried to plot the .dat file. But the form of the file is not in columns and the plotting was not possible. Could you guys help me ?

Here are the first 15 (of the 22,506) lines in the file 'MRprob_1608.dat'. The .TAR file contains 14 .DAT files ranging in size from 102K to 878K. I'm on an old Windows machine and used the '7-ZIP' free software, https://www.7-zip.org to open the .TAR file.
