Refer to the diagrams in par. 7.4 for further details on the reading features.
For Standard and OM models, these
diagrams are taken on various resolution sample codes
at a 25 C ambient temperature and depend on the conditions listed under each diagram.
Subzero model diagrams are based on an ambient temperature of -35 °C and depend on the
conditions listed under each diagram.
