2. TDP AWG meeting, Los Angeles, 2009-05-07 Matt Fleming slide ‹#› of 27 Major Points to Consider In order to compare reflectors the support has to be included. Hydroformed reflector cost is mostly material. Tooling cost gets lost in this project. An offset is 16% more area. 12m has not been done before. Previous 6m reflectors were 4.8mm thick, 12m will be 3.0mm
