'Slewing occurred during this observation' - This message is a warning that because of slewing (e g , target acquisitions, spatial scans, moving targets), the jitter statistics and pattern of jitter and pointing will reflect the telescope motion The statistics will be incorrect - standard deviations will be large
1 Of a gyro, the rotation of the spin axis caused by applying torque about the axis of rotation
(often followed by `of') a large number or amount or extent; "a batch of letters"; "a deal of trouble"; "a lot of money"; "he made a mint on the stock market"; "it must have cost plenty"

DICTIONARY: TYPE=I*4 INSTRUMENT=ALL FILETYPE=OMS UNITS=NONE A discreet flag which indicates that the pointing control system is slewing the telescope while still tracking on guide stars A "1" indicates a slew manuever and "0" signifies stationary tracking Small slews (or "small angle maneuvers) are commanded during target acquisitions and peak-ups, spatial scans, POS TARG activity, real-time maneuvers, and moving target observations A special keyword will appear at the end of the header file when slewing has occurred during the observation window Because of the method of calculation, slewing during an observation will adversely affect the jitter statistics in the header and in the tables Update Rate (in seconds): TLMFORM Update Rate (sec) AN 10 0 FN,PN,H 1 0 CMJ/CMI: All flags are available in both the CMJ and CMI tables If the SLEWING flag is ON at any time during the 3-sec interval, it will appear as ON in the particular row in the CMI table
