Comment on "Surface roughness effect on ultracold neutron interaction with a wall and implications for computer simulations" A. Steyerl et.al., arxiv: 0911.4115v1 [1]

In above mentioned article [1] assumptions of possible systematic errors of our experiment on measuring of the neutron lifetime [2] have been made. In the given comment we are obliged to explain, that assumptions made in [1] are erroneous. They are caused by an inattentive reading of our work [2] and by the improper understanding the methods used in our work [2]. Simulation of experiment [2] carried out in [1] seems to be imperfect and doesn't describe the experimental results. Therefore it is impossible to do any conclusions from such simulation.
