16 December 2013 The tdem_krist_*.zip archives contain code and supporting data associated with the TDEM study "Assessing the performance limits of internal coronagraphs through end-to-end modeling." An archive contains directories for each coronagraph, and subdirectories contain codes, supporting data (e.g. occulter patterns, etc.), and results from running the codes that demonstrate that the milestones were achieved. Each archive also has a maps directory that contains the synthetic surface error maps used by the routines to simulate an aberrated system. Distribution of the codes and results has been approved by JPL New Technology Release #49132. Codes are copyright 2013 by the California Institute of Technology - all rights reserved.
