Changes
*1. Iain has emailed pdf showing optical design and performance. We will go through it and give final go ahead
*2. Iain has gotten received prices for Andor and options will . Will send an email with the options
*3. Kathryn/James showed LJMU CAD design with our slide design incorporated and gave overview
*4. Iain conforms confirms 300um repeatability is acceptable for spectrograph brand broadband filter, no effect on spectra, only flat fielding of imaging is sensitive to position repeatability*5. Iain conformed confirmed 30x30mm filter clear aperture of current design is perfect. No vignetting expected*6. Iain conformed n confirmed for SPRAT LT spectrograph, that the spectograph spectrograph filter is fixed component (doesn’t move in and out of beam)*7. Steward confirm confirms no clash with our HRS/guider pickoff and their calibration pickoff (ours outside SPRAT flange, theirs inside)
*8. We will send current slide design for them to see form factor, we will finalise design in next 4 weeks.
*9. Carel indicated we want API with thrift layer. LJMU agreed that makes sense. Carel and Chris will communicate and clarify software issues.
*10. LJMU will supply computer and software.
*11. We need to double check that new Andor camera can be triggered with GPS like older SHOC models. Iain says they have input for tigger. Spec sheets also stated states external trigger possible.*12. UJMU Steward says the actuators have mounting pieces .Will we use them? They look pretty flimsy apparently.
