This diagram illustrates the effects of floating a box ("inner") and how its "sibling" is forced below it due to the 'clear' property. A document window is shown, with 8 lines (numbered 1 to 8), each 24px high. Text before the "inner" box flows on lines 1 and halfway on line 2. The "inner" box has been floated to the right and occupies the second half of lines 3 and 4. ... The lines, as they appear in the image, contain: 1 Beginning of body contents. ...

... 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. ...
