Other data formats
The data recorded on paper format, fac-similes and sefram, have been inventoried as well after the films.
The fac-similes do not duplicate the data stored on films and represent high resolution printing.
The Sefram sheets essentially correspond to transit observations at fixed frequencies which served to finely tune the NDA performances.
The data stored on magnetic tapes have been lost.
