The bkg keyword is used to perform throughput and emission calculations pertaining to the background signal component of grism observations. In grism observations, a given detector pixel will receive source signal from only a small wavelength interval of the dispersed source spectrum, but it will receive background signal from the entire bandpass of the grism. ... The bkg keyword is only valid when grisms are specified as part of the obsmode. ...

8. Procedures for Observations
... 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. ...

Notes concerning the observations made by UKIRT for the YY Gem programme in March 1988. ... As spot modulation effects are relatively more prominent in V and flare effects in B, it was decided to monitor in K and V during eclipses and in K and B at out of eclipse phases. ... The data were corrected for extinction using the following extinction coefficients: B 0.27, V 0.10, K 0.07, J 0.10 . ...

13. VLTI Calibrator Selection Help Page
The VLTI Calibrator Selector Tool is a tool intended to assist in the selection of suitable interferometric calibrators for VLTI observations with MIDI and AMBER. It uses a model of the VLTI and its instruments to assess the fringe visibility, given the observed bandpass, the geometry, spectrum, and coordinates of the target and the time at which the observations are to be made. ... The tool offers an HTML/Java based interface and consists of two pages. ... The quality flag depends on LDD_chi2. ...
