1. Procedures for Observations
... The J, H and K bands are characterized by a bright background, such a background is mainly due to the emission of atmospheric lines and of thermal radiation. ... If the source cover a large fraction of the slit, spectra off-source must be observed to adequately sample the sky background. ... The on chip integration time (time spent in each position of the slit) must not exceed 40 seconds in J and H bands and 60 seconds in K band. ... We suggest a sequence of 10 for each elementary integration time. ...

4. ON/OFF (Position Switching)
... The procedure simply observes ON your source for x minutes and then takes a `blank sky' observation OFF your source for the same amount of time and tracking the same azimuth and zenith angle range. ... Typically, observing times are kept to within 5 minutes (with 5 minutes as the most efficient, and therefore default, choice). ... If your scans are for 5 minutes or less, your wait time should be set to 1 minute (the default setting). ... A 5 minute ON/OFF + 10s CAL takes 11.3 minutes. ...

10. Accuracy of World positional CCD observations of the numbered minor planets
... Advises . Contact Advises . As an advise for amateurs we would like to underline: if it's possible, try to observe 3 asteroid positions per night and do not neglect to observe the Numbered Minor Planets in your telescope field of view as a "by product" of your observational programs. ... We think such estimations ought to be produced every morning after CCD observations of the moving celestial objects by observer himself. ...
