Fr.: élargissement instrumental
The broadening of a point source caused by the response functions of the telescope and the instrument used.
Fr.: flexion d'instrument
An image defect caused by the mechanical flexure of materials; for example the curved-shape image of a long slit in a spectrograph.

Caftegi, from caftidan "to bend, incline," cafté "curved, bent;" sâzâli, → instrumental.
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
karyâ-ye pâsox-e sâzâl
Fr.: fonction de la réponse instrumentale

In the philosophy of science, the pragmatic view that a scientific theory is no more than a useful instrument or tool for getting our experiences in some order.

1) The design and use of scientific instruments for detection, measurement, control,
computation, and so on.
From → instrument + -ation a combination of -ate and -ion, used to form verbal nouns.
Sâzâlgari, noun from sâzâlgar, → instrumentalist. Sâzâlgân, with plurality suffix -gân.

1) The act or fact of insulating.
Verbal noun from → insulate.
1) A material or an object that does not easily allow heat, electricity,
light, or sound to pass through it.
Âyeq, loan from Ar.
The act, system, or business of insuring property, life, one's person, etc., against loss or harm arising in specified contingencies, as fire, accident, death, disablement, or the like, in consideration of a payment proportionate to the risk involved (Dictionary.com).

1) bimé kardan; 2) dartenzidan
1) To provide or obtain → insurance on or for.
Variant of → ensure.
Same as → integer number.
From L. integer "whole," literally "intact, untouched," from → in- "not" + root of tangere "to touch."

1) dorost; 2) dorostâl
Fr.: 1) intégral; 2) intégrale
1) Consisting of whole numbers or integers.
Integral, from M.Fr. intégral, from M.L. integralis "forming a whole," → integer "whole."
1) Dorostâl, from dorost "whole, complete; healthy; right," related to
dorud "benediction, praise, thanksgiving," from
Mid.Pers. drust "whole; healthy; well, right," drôd "health, thriving;"

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.
