N. Mori reported about the HerdSoftware status (see slides).

E. Catanzani reported about preliminary anisotropy studies (see slides). * G. Ambrosi asked about what to do when the CSS orbit will be available. E .Catanzani   answered that replacing the ISS orbit with the CSS orbit for this study will be easy   and quick. M. Xu added that for now we can use the TG2 data since there is still no clue   about the CSS data. M. Xu will send the TG2 info to E. Catanzani. * M. Xu asked about backgrounds. E. Catanzani replied that the study is still preliminary   and that in future developments the backgrounds from protons and helium will be considered.   Monte Carlo files have to be produced for this. M. Duranti added that for DAMPE at 1 TeV   the residual background is about 10%, and a better figure is expected for HERD so it should   not be an issue. A. Tykhonov added that depth is probably not a factor for saying that HERD   will be better than DAMPE in this aspect. * J. Casaus pointed out that many information needed by these studies have been studied by the   trigger working group. E. Catanzani agreed that it would be useful to use that information in   this study.

X. Liu reported about the implementation of the CSS structure in simulation (see slides).

V. Vagelli reported about the workplan for calorimeter reconstruction (see slides). * I. De Mitri asked about the long. skewness plot on slide 4. V. Vagelli answered that the shape   for electrons is due to a wrong assignment of the shower development direction. * I. De Mitri asked about fitting the longitudinal profile with an analysitcal function. V. Vagelli   answered that for now the standard function is being used for electrons and that no work   on this aspect has been done yet for protons.
