IRAC-2B Technical Reports


Listed below are some reports discussing the performance of IRAC-2B. These reports are typically based on laboratory measurements, daytime measurements at the telescope, data obtained during test and reserved nights, and data provided by observers.

Report on Test Observations XI

Written November, 5 1997.

Discusses the Gain, RON, dark current, bad pixels and non-linearity of the detector array.



Report on Test Observations X

Written March, 21 1997.

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.



Report on Test Observations IX

Written February 4th, 1997.

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.

Report on Test Observations VIII

Written November 27th, 1996

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.



Report on Test Observations VII

Written August 23, 1996

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.



Report on Test Observations VI

Written January 5, 1996

This report discusses the alignment of the camera and filters, discusses electronic interference and presents a bad pixel map.


Report on Test Observations V

Written December 12, 1995

This report discusses the alignment of the camera, and the effect that defocussing has on flux calibration.


Report on Test Observations IV

Written October 26, 1995

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.


Report on Test Observations III

Written August 20, 1995

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.


Report on Test Observations II

Written June 28, 1995; corrected March 12, 1996

This report presents the non-linearity and the dark current of the array, discusses flat fielding and measures the wavelength shift across the FP.


Report on Test Observations I

Written May 31, 1995

This report presents the non-linearity of the array, discusses flat fielding and presents a measurement of the sky background.
