Field Distortions in the CPC 2 Plate Data
Residuals of a conventional plate adjustment of 5,687 plates of the Second Cape Photographic Catalogue (CPC2) using the Southern Reference Star (SRS) Catalog were analyzed to search for systematic errors depending on the location of the star images on the plate. Even after correcting for third order optical distortion, such coordinate depending systematic errors, hereafter called field distorti...
متن کاملConcurrent Field Monitoring Removes Distortions from In-Vivo DWI data
Introduction: In diffusion-weighted (DW) MRI, eddy current effects notoriously result in geometrical image distortions. This is problematic since variably diffusionencoded data must be perfectly congruent to permit fitting diffusion models such as the diffusion tensor. In modern MR systems extensive efforts are made to address this problem by optimized gradient coil and amplifier design, model-...
