ChangeLog for eboxdetect =============================== Version 4.25.1 - 2015-10-01 (IT) -------------- + Input data in detector coordinates: Use CDELT1L, CDELT2L header keywords instead of CDELT1, CDELT2 in order to determine the pixel size. For pn and MOS images in detector coordinates, CDELT1/2 have different units. Version 4.25 - 2015-08-21 (IT) -------------- + Allow input data in detector coordinates (SCR 7289). The coordinate system is determined from the keywords CTYPE1/2 (new arguments to the subroutine co_image): detector coordinates, if DETX/Y. No PSF correction is performed in this case. Detector coordinates of the detections are written to new DETX/DETY columns in the output source list (only!) for input images in detector coordinates. Note: Position errors are not converted into detector coordinates. If required, users can derive them from the X_IMA_ERR, Y_IMA_ERR columns. + Documentation updated. Version 4.24 - 2015-03-31 (IT) -------------- + new parameter "obsmode" to distinguish between pointing and slew-mode data (SCR 7279). Default: pointing. + eboxdetect_mod.f90: use a flat kernel + eboxdetect_mod.f90: Improved detection of faint extended sources. subroutine msrbkg: Calculate preliminary equivalent likelihoods of the candidate sources. subroutine match: If irun (i.e.: ncom) > 1, check whether a newly detected candidate has a counterpart in the previous version of the source list AND (new:) whether the equivalent likelihood of the counterpart is above the detection threshold likemin. A previous detection with a likelihood below likemin can be overwritten by a new one now. Otherwise, it might be removed from the final source list because of its low detection likelihood, and faint extended sources might be missed. + documentation updated Version 4.23 - 2014-08-28 (IT) -------------- + DEPEND: updated to emldetect-6.0 + edetect_io_box.f90, documentation: fixed typo in error messages. + edetect_io_box.f90: changed syntax of cp_head to be consistent with other source-detections tasks (call setAttributes). No effects on eboxdetect output. Version 4.22.5 - 2013-03-17 (IT) -------------- + Documentation updated. Minor latex syntax changes to build the package index properly on Ubuntu Version 4.22.4 - 2012-06-22 (IT) --------------------------------- + eboxdetect_mod.f90: fixed a bug which made eboxdetect crash when a source is detected exactly at the position (image pixels) of the optical axis. Version 4.22.3 - 2012-06-18 (IT) --------------------------------- + Documentation: Typographical and formal corrections, fixed broken Errors Section. Version 4.22.2 - 2012-03-27 (IT) ------------------------------- + Marked parameter mergedlistset as "not yet implemented" in documentation and parameter file (SPR-6571) + Added parameter descriptions to documentation (withimagebuffersize, imagebuffersize, SPR-6700) + Removed unused imagebuffersizesets entry from parameter file: parameter is "imagebuffersize" (SPR-6700) Version 4.22.1 - 2011-02-14 RDS ------------------------------- + src/edetect_io_box.f90 Now checks for the mask in an extension called MASK and if it doesn't find it, looks in the PRIMARY array. (SCR-314) Version 4.22 - 2010-03-11 JR ------------------------------- Implemented the withimagebuffersize parameter. This is for the use or not of the imagebuffersize parameter, meant to be used in the reduction of memory requirements. Default value=no. With the default value the imagebuffersize parameter will be read from the header of the image. This also fix the edetect_chain problem. Version 4.21 - 2009-05-06 JR ------------------------------- Fixed DEPEND file. Now emldetect 5.0 Version 4.20 - 2009-03-31 JR ------------------------------- Implemented reduction of memory requirements for raster scan data new parameter: imagebuffersize, default value=640 Version 4.19.2 - 2008-06-03 GL ------------------------------- Removed test output Version 4.19.1 - 2008-05-08 GL ------------------------------- Increased limits for input images (for mosaicing observations): max_ima=240 max_ins=60 Enable processing of multiple exposures with identical ObsIDs: increased lenghts of strings expid, ins, instrume Close SOC-SPR 5874 (SSC-SPR-3139) Correct error due to integer variable 'iso', which should be of real type after the changes made in v4.16. The error resulted in a slightly reduced sensitivity for faint sources.

Version 4.13.3 - 2004-10-06 GL ------------------------------- Average input background map over detection box Close SPR SSC-SPR-3399: Spurious sources near chip gaps. Version 4.13.2 - 2004-08-25 GL ------------------------------ Total likelihoods in multi-instrument runs are now corrected using the effective number of input images (where the source is inside the detection mask).
