7. Apply changes to RAT Hit Apply on the Schedule Menu. This will apply the configuration settings and
begin the Star Calibration. The telescope will move from star to star, center the image, then move to the
next star. If the software cannot find a star after several attempts to capture the star image, the
operator should use the
Next Star button on the Star Calibration menu on RAT.
8. Verify that the meteorological data is being logged properly Values for the pressure, temperature,
wind speed, etc. should all be within normal ranges.
9. Verify the RMS value Once the system has processed 50 stars, a series of windows will pop up. The
last window that pops up will contain the RMS values of the Star Calibration. Scroll down in the window
to view the calculated RMS value (Figure 5 4). If the solution is <3.5 RMS, the changes will be
automatically applied to the mount model when the user exits POP, and will need to be verified as
described in Section 5.2.2. Otherwise, the attempted Star Calibration will be rejected and will need to
be re run from the beginning of the procedure.
