CIAO 2.2.1 Release Notes
This CIAO release includes several new and updated instrument specific tools and data manipulation tools (e.g. acisreadcorr, dmjoin, mkrmf with weighting option, mkwarf, rmfimg, etc.), plus new and enhanced functionality within the SHERPA (ahelp/sherpa.html) modeling and fitting application and the CHIPS (ahelp/chips.html) plotting and imaging application. Editing capabilities have been added to PRISM (ahelp/prism.html) and the VARMM (ahelp/varmm.html) interface library has been extended.
- User Infrastructure
dmcopy / dmlist / dmstat - Fix for region problems with PIE and SECTOR filtering and some of the area problems. mkpsf - Fix for autonaming for individually extracted images dmextract - minor tweaks to wmap parameter comment (det=32). - Fix for crash if user supplied stack of background regions. - Users can now supply an additional filter to wmap that is indepent of filter applied to input file (eg create wmap in a specific energy range). - Fix for region problems with PIE and SECTOR filtering and area problems. dmfilth - Fix for bug that gives wrong answers for non-square images dmsort ** UPDATE ** - Completely re-written and available now as a stable stand-alone tool. - No restriction on the number of input rows as before. - Fast for files that are 'almost' sorted. dmtcalc - Fix for bug that prevented creating/updating columns with the same name as existed in input file(s). dmmerge - Additional checks on the array size and dimensions for input files. reproject_events - Speed improvements psf_project_ray - Fix to work with recently updated focal length sso_freeze - Fix to the TLMIN/TLMAX keywords that prevented the image in object-centered coordinates from being displayed properly in ds9 tgdetect - Changed default cellsize from 0 to 15 so that celldetect will not use the PSF library to determine cellsize. A fixed cellsize of 15 pixels has been found to be most effective for the majority of data processed. add_grating_spectra - Fix for cleaning up temporary files at the end of the script. psextract - Minor bug fix to deal with CONTENT header keyword to determine which type of aspect files were provided.
- Background filtering has been improved to allow separate instrument models and independently grouped background data. - fakeit can now simulate data with a source model only, using the "dataspace" command. - Several minor plotting improvements have been implemented.
DS9 - DS9 v2.0b4: supported in chips, prism, filtwin, and sherpa Prism - Fixed several PRISM keyword viewing and editing bugs ISIS - ISIS ots upgrade from v0.9.51 to v0.9.61 Documentation - XML documentation - server HTML page(s) verified W3C compliant - corrected problem display of minus/plus in position mkoif - Corrected mkoif to disregard +x permission on input files Setup Scripts - Improved message for unsupported platforms in ciao.*sh setup scripts
