***Mechanical data: 
Each experiment has a .txt file having the experiment number as name. The data are tab separate file, each column is a variable as follow:
	Column 1: Time(s)
	Column 2: Normal_stress(MPa)
	Column 3: Shear_stress(MPa)
	Column 4: friction
	Column 5: Shear_disp(mm)
	Column 6: Normal_disp(mm)
The experiments performed on Fontainbeleau sandstone bare surface at constant velocity are:
	b1089: 3 μm/s
	b1094: 30 μm/s
	b1096: 100 μm/s
The velocity step experiments performed on quartzite bare surface are:
	b1179: 3-30 μm/s
	b1178: 3-100 μm/s
	b1180: 3-300 μm/s
The velocity step experiments performed on Fontainebleau sandstone bare surface are:
	b1134: 3-30 μm/s
	b1114: 3-100 μm/s
	b1124: 3-300 μm/s
	b1113: 3-100 μm/s (velocity step every 2 mm)

	b1145: 3-30 μm/s
	b1143: 3-100 μm/s
	b1144: 3-300 μm/s

*** Rate-and-state inversion data:
Each velocity step experiments has a .xlsx file containing the inversion of each velocity steps. The name of the file containe the experiment number.
Both ageing and slip law inversion are in each file (left table is ageing law, right table is slip law). Data are as follow:
	Column A: Record Number at onset of velocity step
	Column B: load point displacement at onset of velocity step (mm)
	Column C: V0  (µm/s)
	Column D: Upstep V (µm/s)
    Ageing law:
	Column E: µ0
	Column F: deviation µ0
	Column G: a 
	Column H: deviation a
	Column I: b
	Column J: deviation b
	Column K: Dc (µm)
	Column L: deviation Dc (µm)
	Column M: k (/um)
	Column N: deviation k (/um)
	Column O: R2
    Slip law:
	Column Q: µ0
	Column R: deviation µ0
	Column S: a 
	Column T: deviation a
	Column U: b
	Column V: deviation b
	Column W: Dc (µm)
	Column X: deviation Dc (µm)
	Column Y: k (/um)
	Column Z: deviation k (/um)
	Column AA: R2
    Column AC: Comment on fitting
