Approximate correction for parallel CTI in GRADED mode data
نویسنده
چکیده
Abstract We show the ACIS trap maps developed for the CTI correction algorithm can be applied to the GRADED mode data. The technique uses the fltgrade information available in the GRADED mode telemetry, and average 3 × 3 PHAS images for each fltgrade pre-calibrated using the FAINT mode data. The results (recovery of photon energies and energy resolution) are nearly identical to those from the CXC CTI corrector implemented in acis_process_events.

The front-illuminated (FI) CCDs in the Advanced CCD Imaging Spectrometer (ACIS) on the Chandra X-ray Observatory (Chandra) were damaged in the extreme environment of the Earth’s radiation belts, causing charge traps that result in enhanced charge transfer inefficiency (CTI) during parallel readout. This causes row-dependent gain, event grade ‘morphing’ (spatial redistribution of charge) and ene...
متن کاملAn Analytical Shear Factor for FGM Circular Plates with Non-uniform Elastic Foundations and Normal and Shear Tractions
The available shear correction factors have mainly been developed for homogeneous isotropic plates and/or assuming that no shear tractions are imposed on the top and bottom surfaces of the plate. In the present research, a more general case of a circular functionally graded plate subjected to non-uniform normal and shear tractions at the top and bottom surfaces is considered. These non-uniform ...
متن کاملIn-Plane Analysis of an FGP Plane Weakened by Multiple Moving Cracks
In this paper, the analytical solution of an electric and Volterra edge dislocation in a functionally graded piezoelectric (FGP) medium is obtained by means of complex Fourier transform. The system is subjected to in-plane mechanical and electrical loading. The material properties of the medium vary exponentially with coordinating parallel to the crack. In this study, the rate of the gradual ch...
متن کاملSTIS Model Based Charge Transfer Inefficiency Correction
The STE-CF Calibration Enhancement effort for the Space Telescope Imaging Spectrograph (STIS) aims to improve data calibration via the application of physical modelling techniques. As part of this effort we have developed a model of the STIS CCD readout process that is able to correct STIS data for charge transfer inefficiency (CTI). The model itself is described in some detail in earlier ISRs....
متن کاملA Zigzag Theory with Local Shear Correction Factors for Semi-Analytical Bending Modal Analysis of Functionally Graded Viscoelastic Circular Sandwich Plates
Free bending vibration analysis of the functionally graded viscoelastic circular sandwich plates is accomplished in the present paper, for the first time. Furthermore, local shear corrections factors are presented that may consider simultaneous effects of the gradual variations of the material properties and the viscoelastic behaviors of the materials, for the first time. Moreover, in contrast ...
