Modified applications

The following applications have been modified:

CONTOUR

• It is now possible to draw `pseudo-contours' which outline regions of the data array chosen in ways other than than by simple data thresholding. Setting MODE to "Good" will produce a `contour' which encloses all the good pixel values. Setting MODE to "Bounds" will produce a curve which traces the edges of the array.
• A new Parameter LABPOS has been added which controls the position of labels produced when drawing outlines using modes "Good" and "Bounds".
• The number of pen colours used in a cycle if PENROT is set TRUE has been increased from 3 to 5.

FILLBAD

• A bug has been fixed in FILLBAD which caused the MEMORY=YES option to produce incorrect results.

FITSEDIT

• FITSEDIT and FITSTEXT both now allow blank keyword values to be supplied. They also allow the equals sign to be omitted so long as the keyword value is blank.
• A bug has been fixed which caused comments to be lost if they abut the keyword value in the text file.

WCSATTRIB

• WCSATTRIB now reports an error if an attempt is made to change attribute values in any of the Frames which are managed internally by the NDF library (that is, Frames with Domains PIXEL, AXIS, and GRID). The exception to this is that the Domain  attribute itself may be changed, thereby adding a new Frame to the WCS component.
