- Daily alignment of visbeams, dichroics, and M10. The green laser is now bright enough for these steps to be done using the standard CHARA procedures. LDCs should be in place and homed for all telescopes being used by PAVO. It is recommended that the IR beams be aligned to CLIMB on Beams 1-3, in case CLIMB is needed to help search for fringes. | - Daily alignment of visbeams, dichroics, and M10.
