We obtain the gas velocity fields by placing three parallel and adjacent VLT/FORS2 slits on each galaxy. To quantify irregularities in the gas kinematics, we use three indicators: the standard deviation of the kinematic position angle (σPA), the mean deviation of the line of sight velocity profile from the cosine form which is measured using high order Fourier terms (k3,5/k1) and the average misalignment between the kinematical and photometric major axes (Δφ). These indicators are then examined together with some photometric and structural parameters (measured from HST and FORS2 images in the optical) such as the disk scale length, rest-frame colors, asymmetry, concentration, Gini coefficient and M20 . Our sample consists of 92 distant galaxies. 16 cluster (z∼0.3 and z∼0.5) and 29 field galaxies (0.10≤z≤0.91, mean z=0.44) of these have velocity fields with sufficient signal to be analyzed. To compare our sample with the local universe, we also analyze a sample from the SINGS survey. Description: Our spectroscopic observations were spread across 5 nights in October and November 2004 for Cl 0412, 7 nights in December 2005 and February 2005 for MS 1008, 5 nights between May and July 2005 for MS 2137. For photometric data, we use both VLT/FORS2 and HST/ACS images. We obtained imaging of the MS 1008, MS 2137 and Cl 0412 samples in the ACS/F606W filter while we exploited existing imaging of MS 0451 in the ACS/F814W filter from the ST-ECF HST archive. Ground based images were taken in the B, V, R and I filters for the whole sample. The FORS2 filters B, V and I are close approximations to the Johnson-Cousins photometric system while the R filter is a special filter for FORS2 that is similar to the Cousins R . File Summary:

Note (1): Individual notes: 1F11 = The redshift of galaxy 1F11. As a result, for this galaxy, Rc/Rd is given in arcseconds. 1C10 = The surface brightness profile of galaxy 1C10 is much more extended on one side of the galaxy than on the other side. Therefore the scale length and total magnitude of the disk given in the table are not reliable. This galaxy was excluded while calculating the correlations between the disk scale length and the irregularity in the gas kinematics.
Global Notes: Note (G1): Re/Rd is given in arcseconds in case the redshift of a galaxy is unknown. Note (G2): The asterisk indicates choices of the photometric zero point: * for F606W: Zp(F606W)=26.398mag * for F814W: Zp(F814W)=25.492mag (Bedin et al., 2005MNRAS.357.1038B)
