| 691 | 2009-05-03 | Depositing the first portion of the Fobs data CIFs. These are CIFs from the Acta Cryst. journals, where the correspondence of the coordinate CIF and the Fobs CIF could be unambiguously determined automatically. In these files, cell constatnts match exctely, being equal with the floating point '==' operator in Perl. For the future depositions, such requirement is too strict, since sometimes cell constants in the coordinate and the Fobs files differ by a rounding error. Thus, a small tollerance will have to be introduced into the COD Fobs deposition scripts. |
