This archive contains fits tables providing 2D maps of single stellar population (SSP) parameters for the Atlas3D sample.
These values were used in generating the parameter radial profiles used in Krajnovic et al. 2020. The SSP parameters were
measured as per McDermid et al. 2015 (MNRAS, ), making use of the Schiavon (2007) stellar popuation models, and the emission-corrected
absorption line indices associated with McDermid et al. (2015), available through the Atlas3D website (www.purl.org/atlas3d).

The fits tables provided here contain the following column headings / structure names:

NAME	  - Name of galaxy
XS	  - X-position of voronoi bin centre
YS	  - Y-position of voronoi bin centre
Age	  - SSP-equivalent age (Gyr)
esupAge	  - Upper 1-sigma error on age (Gyr)
einfAge	  - Lower 1-sigma error on age (Gyr)
eAge	  - Mean symmetric error on age (Gyr)
Z	  - Total metallicity, [Z/H] in solar units
esupZ	  - Upper 1-sigma error on [Z/H] 
einfZ	  - Lower 1-sigma error on [Z/H]
eZ	  - Mean symmetric error on [Z/H]
Alpha	  - [Alpha/Fe], in solar units
esupAlpha - Upper 1-sigma error on [alpha/Fe] 
einfAlpha - Lower 1-sigma error on [alpha/Fe]	
eAlpha	  - Mean symmetric error on [alpha/Fe]

Here is an example of how to plot the data in IDL (assuming the NASA/IDL Astrolib library is also availble):

tab = mrdfits('SSP_bin_MS_NGC2974.fits',1)
rad = SQRT(tab.xs^2 + tab.ys^2)
plot,rad,tab.age,psym=2
