Discusses the Gain, RON, dark current, bad pixels and non-linearity of the detector array.
Discusses telescope tracking, pointing and offsetting; discusses the guiding accuracy of the autoguider; reports on the latest sensitivies for J, H, K and K' broad band imaging and warns that the filters BP2, BP10 and BP11 suffer from internal reflections.
This report discusses the performance of the telescope, presents the most
recently measured throughput of the detector, and discusses the transformation
between the natural filter set of IRAC2 and the Carter System.
This report discusses image quality, the oscillation in the RA axis, focus
offsets, the dependence of the illumination correction with telescope position,
and the variation of the PSF over the field of view for lenses LB and LC.
This report discusses the sensitivity of all filters used with IRAC2b, the
evolution of the sensitivity with time and the constancy of the illumination
correction with telescope position.
This report discusses the alignment of the camera and filters, discusses electronic interference and presents a bad pixel map.
This report discusses the alignment of the camera, and the effect that defocussing has on flux calibration.
This report presents a measurement of the wavelength shift across the FP, lists the filter transformation equations between the Carter system and the natural IRAC2b system, and compares the sensitivities of lenses LA, LB, LD, and LE relative to lens LC.
This report discusses flat fielding, shows how to achieve calibrated data with the FP, lists the filter transformation equations between the Carter system and the natural IRAC2 system, and lists measurements of the sky background.
