-           * The bottle supplying isobutane (C<sub>4</sub>H<sub>10</sub>) for the CRDCs is secured to the south support post for the focal plane chamber. It sits on a scale for monitoring the isobutane consumption – the electronic display for the scale sits on the chiller unit under the focal plane chamber.
