Figure 10. Leg numbering (overhead view).
(46) Repeat (27) through (37) above and record readings on new test data sheet for
leg number 1. (Mark an X in Leg Number 1 block of test data sheet for Reference
Mirror in place.)
(47) Close MIRROR OPTICAL BAFFLE and open UPPER MIRROR OPTICAL
BAFFLE (fig. 8).
(48) Repeat (40) and (41) above.
(49) Perform computations listed on test data sheets. If TI computed deviation is
greater than 3.71 as indicated on test data sheets, retest and repair as necessary.
(50) Remove GAGE BLOCK No. 1 from LEG NUMBER 1 and place GAGE BLOCK
No. 1 under LEG NUMBER 2 (fig. 10).
(51) Move REFERENCE MIRROR (fig. 7) to in position. Do not lock REFERENCE
MIRROR (fig. 7) into position.
(52) Close LOWER MIRROR OPTICAL BAFFLE and open UPPER MIRROR
OPTICAL BAFFLE (fig. 8).
(53) Repeat 27 through 37 above and record readings on new test data sheet for leg
number 2. (Mark an X in Leg Number 2 block of test data sheet.)
(54) Repeat (52) above.
(55) Repeat (40) and (41) above.
(56) Perform computations listed on test data sheets. If TI computed deviation is
