... 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. ...

You can also sort on a specific part of a field if necessary. To define which part of a field to sort on you give the position in the field at which to start the sort followed by the position in the field at which to end the sort. The position at which to start the sort is given as the number of fields to skip followed by the number of characters to skip. ... tells sort to skip the first two fields and the first three characters of field 3. ...
