... The source-list file produced by omdetect contains a list of the positions of all the detected sources, the parameterizations of their shapes, their extracted count-rates, and corrected count-rateswhich contain some of the corrections that are needed to convert the raw rates to the rates that can be used to compute instrumental magnitutes. Fully corrected count-rates and instrumental magnitudes are obtained by running ommag , with its parameter `` set '' set to the omdetect source-list. ... none . ...

Next: Combining Bias Frames Up: Preparing Your Calibration Previous: Input and Output .

... 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. ...
