= Twilight Imaging v01 =

= Twilight images with CWFS, PV =


Purpose:  We have seen some shift in the position of the pupil when the DWFS8
was remounted.   We would like to document if there are any temperature
affects.

Procedure:  [[BR]]
            1)  Move the dome and structure to 0 (155 if wind is an issue)[[BR]]
            2)  Move the tracker to the center on sphere (0,0,0,0,0,0)[[BR]]
            3)  Move out the ACQ arm and move in the CWFS arm[[BR]]
            4)  Move the slide to the CWFS and save twilight image (flux ~150)[[BR]]
            5)  Move the slide to the PV and save twilight image (flux ~150)[[BR]]
            6)  record all required data and move images to the NWD[[BR]]

Data to save  [[BR]]
              1)  Save the data dump[[BR]]
              2)  Save the names of the twilight images saved[[BR]]
              3)  Save the truss temp[[BR]]
