... 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. ...

... The zeta function of the classical monodromy transformation of the germ $f$ is a topological invariant of it. Let us consider a parametrization (uniformization) of the curve $(C,0)$. The order of a function on $(C,0)$ as a function in the uniformization parameter defines a decreasing filtration on the ring of functions on the curve singularity. It appears that the Poincare series of this filtration (considered as a rational function) coincides with the zeta function mentioned above. ...
