We provide the tabulated data and fits files of the mean disks (1-D) and bars (2-D) discussed by Diaz-Garcia, S. et al. (2016) 
("The stellar mass distribution of S4G disk galaxies and the signatures of bar-induced secular evolution"). 
We averaged 1-D stellar density profiles, the stellar contribution to the circular velocity, and we obtained 2-D bar stacks in bins of total stellar mass, Hubble stage and galaxy family. 
From the bar stacks, we calculated the azimuthally averaged luminosity profiles, the tangential-to-radial forces and the m=2,4 Fourier amplitudes. 
We also applied ellipse fitting to derive the ellipticity and b4 radial profiles of the bar stacks.

Here, we explain the terminology used to label and store the ".txt" and ".fits" files, in relation to their content:

The term "_starmass_" is used when the binning was based on the total stellar mass of the galaxy from Munoz-Mateos et al. (2015). We indicate the common logarithm of the boundaries (8.5,9.9.5,10,10.5,11). 
The term "_ttype_" is used when the binning was based on the Hubble stage of the galaxy (-3,0,3,5,8,11) from Buta et al. (2015).
The term "_family_" is used when the binning was based on the morphological family of the galaxy (_AB,AB,A_B,B) from Buta et al. (2015).
The term "_hr_" is used when the 1-D stacks were obtained as a function of the disk scalelength (from Salo et al. 2015).
The term "_kpc_" is used when the 1-D stacks were obtained as a function of disk size in physical units (kpc).
The term "_barred_" is used when only barred galaxies are stacked (according to Buta et al. 2015).
The term "_unbarred_" is used when only non-barred galaxies are stacked.

The fits files of the bar stacks are in units of flux (MJy/sr), and the pixel size is 0.02 x rbar (where rbar refers to the bar radius).

The stored files are the following (the boundaries of the different bins are referred below with asterisks):
