... 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. ...

... Because of the potential impact of poor weather on 3mm observations, the ATCA has used a "swap" system of flexible scheduling for these observations. ... This was both to encourage more proposals that could be used as swaps and to reduce the burden of swapping (the swap system tends to discriminate against the centimetre observer). ... For example Directors Time could be used for 3mm proposals if there was no bad weather (this would not be possible if a centimetre swap were mandated). ...

... An OBJECT column gives the name of the object observed (usually a star name). ... In critical cases, it is common practice to measure sky on two or more positions around a target object, and these positions must be identified. ... A general treatment of this problem requires a column called OBJECT, bearing the usual name of the object (as in the star tables); a column labelled STARSKY, to distinguish between star+sky, star alone, or sky alone; and additional columns to identify the sky position. ...
