On the test of the modified BCS at finite temperature
  The results and conclusions by Ponomarev and Vdovin [Phys. Rev. C {\bf 72}, 034309 (2005)] are inadequate to judge the applicability of the modified BCS because they were obtained either in the temperature region, where the use of zero-temperature single-particle spectra is no longer justified, or in too limited configuration spaces.
