Data taking in Virtual Control Room: the SNfactory example

Virtual Control Room allows a team of people in various locations to contribute fully to an instrument acquisition: a reduced support is required on site but, due to the large support available off site, the data taking quality can be still better compared to the usual on-site support scheme. The acquisition of the SNfactory spectro-photometric follow-up is based on such data taking model. This acquisition and its performances are presented here.
