| dc.description | We consider open superstring partition function Z on the disc in time-dependent tachyon background T = f(x<sub>i</sub>)e<sup>μx<sub>0</sub></sup> where the profile function f depends on spatial coordinates. We compute Z to second order in derivatives of f and compare the result with some previously suggested effective actions depending only on first derivatives of the tachyon field. We also compute the target-space stress-energy tensor in this background and demonstrate its conservation for the linear profile f = f<sub>0</sub>+q<sub>i</sub>x<sup>i</sup> corresponding to a marginal perturbation. We comment on the role of the rolling tachyon with the linear spatial profile in the decay of an unstable D-brane. |
