Fr.: magnitude instrumentale
The magnitude derived directly using → Pogson's relation. The instrumental magnitude depends on → detector→ sensitivity, telescope → aperture, exact filter → bandpass, etc. It must be → calibrated to some standard → photometric system.
Fr.: profil instrumental
The shape of instrument's response to the input signal. The Fourier transform of the source function by the instrument function.
instrumental response function

integral field spectroscopy
binâbnemâyi-ye dorost-e meydân
Fr.: spectroscopie intégrale de champ
A technique in spectroscopy for recording a spectrum from each point of an extended object. The field of view image is divided into a multitude of small components using different methods, e.g. lenslet arrays, fiber bundles, or image slicers. From each component a spectrum is extracted or an image is reconstructed at a particular wavelength.
Fr.: fonction intégrale
A function whose image is a subset of the integers, i.e. that takes only integer values.
Fr.: opérateur intégral
