# Category MAP

Name:
`'map'`

Description:

           Data items in the MAP category record
                  the details of a maps. Maps record values of parameters,
                  such as density, that are functions of position within
                  a cell or are functions of orthogonal coordinates in
                  three space.

                  A map may is composed of one or more map segments
                  specified in the MAP_SEGMENT category.

                  Examples are given in the MAP_SEGMENT category.

Example:

Example 1 - Identifying an observed density map and a calculated density map

            loop_
            _map.id
            _map.details

            rho_calc
       ;
            density calculated from F_calc derived from the ATOM_SITE list
       ;
            rho_obs
       ;
            density combining the observed structure factors with the
            calculated phases
       ;
