Release Notes--V0.13-6

No new applications or facilities have been introduced or changed, but the following bugs have been fixed:

• ARDMASK  now sets the bad pixel flag in the output NDF so that other applications interpret the selected pixels as bad.

• COMPAVE  now traps zero variance values, preventing a divide by zero error.

• CONTOUR  no longer draws contours in the background colour if the requested contour colour is not available on the selected device. This previously could cause contours to be invisible when using a monochrome PostScript device.

• CONTOUR no longer core dumps if an abort (!!) is given for Parameter PERCENTILES.

• History information written to NDFs now contain the up-to-date KAPPA package version number.

• DISPLAY  now uses independent compression factors for both axes. Previously, an inappropriate compression factor could be used for one of the axes if the lengths of the two axes were very different. Also, the default value for MARGIN used when annotated axes are produced, has been changed from 0.16 to 0.2 in order to avoid clipping of labels on certain devices.

• Trailing spaces are now stripped from the Title  attribute of the current WCS Frame.

• A bug in MATHS  which could cause zero variances to be produced sometimes when using double precision data has been fixed.

• NOMAGIC  and FILLBAD  now set the bad-bits flag  in the output NDF to zero. Previously, NDFs containing QUALITY arrays could still seems to contain bad pixels after running NOMAGIC or FILLBAD. This no longer happens.

• WCSREMOVE now issues a warning instead of aborting if an attempt is made to remove the Base Frame of the WCS FrameSet.

• NATIVE  now correctly replaces IEEE NaN and Inf values by Starlink bad values on Solaris systems.

• The global Parameter POSITIONS_LIST has been replaced by CATALOGUE.
