Modified Commands

The following applications have been modified:

APERADD

• Parameter QUIET has been withdrawn. Instead set the MSG_FILTER environment variable to QUIET to suppress display of the statistics.

BEAMFIT

• Parameter QUIET has been withdrawn. Instead set the MSG_FILTER environment variable to QUIET to suppress display of the fit parameters.
• The map of residuals now contains the normal `data minus fit' evaluations rather than the reverse sense.
• The total background-subtracted data sum in the multi-Gaussian fit is now written to the output parameter SUM.
• After a bug fix it is now possible to fit beams within an arbitrary plane of a cube.
• Relax a constraint to cater better for a poor initial position.

BLOCK

• The dimensionality restriction is now lifted. This enables, for example, smoothing of a data cube in all its dimensions simultaneously. As a consequence the AXES parameter is withdrawn. However, you can replicate its function by setting one of the three BOX-parameter sizes to 1 to specify the axis not being smoothed; the remaining two BOX values of 3 or more define a plane that is smoothed independently for all parallel planes. The independent smoothing of axes is now generalised, so for example, you can smooth all lines in an image or cube; or all lines, planes, or cubes in a hypercube.
• It reports the input NDF's dimensionality if it is more than one, before prompting for Parameter BOX.

CENTROID

• Parameter QUIET has been withdrawn. Instead set the MSG_FILTER environment variable to QUIET to suppress display of the centroid positions.

CHANMAP

• Fix bug whereby Cmean and Csigma estimators were not amongst the allowed options.
• Allow ESTIMATOR=Median to operate on just three channels.

COPYBAD

• The output NDF inherits data type of the input NDF, instead of the NDF given by Parameter REF.

CREFRAME

• Parameter QUIET has been withdrawn. Instead set the MSG_FILTER environment variable to QUIET to suppress display of the Gaussian parameters in GS mode.

CURSOR

• Parameter QUIET has been withdrawn. Instead set the MSG_FILTER environment variable to QUIET to suppress display of the positions.

FFCLEAN

• Parameter ILEVEL has been withdrawn. Instead use the MSG_FILTER environment variable to control the output messages.
• Now works with double-precision data.

FITSLIST

• New Parameters ENCODING and FULLWCS allow the list of displayed FITS cards to include cards derived from the NDF WCS component, in addition to those read from the FITS extension.

HISTAT

• Works for data ranges smaller than the type precision.
• The minimum sparseness increased from 4 to 16 percent to cope with extreme outliers, at the cost of poorer handling of quantized distributions.
• Generates a new histogram between any narrowed value limits to yield more-accurate statistics.

HISTOGRAM

• This now displays an improved x-axis label on its plot.

LINPLOT

• The y-axis Symbol has changed from the NDF's label to the name of its plotted array component. A long Symbol including spaces caused issues in other tasks like CURSOR, where the Symbol is used as a column name in the output catalogue.

LISTSHOW

• Parameter QUIET has been withdrawn. Instead set the MSG_FILTER environment variable to QUIET to suppress display of the positions.

LOOK

• Parameter QUIET has been withdrawn. Instead set the MSG_FILTER environment variable to QUIET to suppress output messages.
• A bug has been fixed that caused logfile output to be truncated to 255 characters per row even if MAXLEN was greater than 255.

MSTATS

• Parameter ILEVEL has been withdrawn. Instead use the MSG_FILTER environment variable to control the output messages.
• Fix bug whereby Cmean and Csigma estimators were not amongst the allowed options.
• Allow ESTIMATOR=Median to operate on just three NDFs.

NDFCOPY

• There is a new COMP parameter that permits the QUALITY or VARIANCE components or the errors (square root of the VARIANCE) to become the DATA_ARRAY in the output NDF.

NDFTRACE

• Parameter QUIET has been withdrawn. Instead set the MSG_FILTER environment variable to QUIET to suppress display of the NDF's attributes.

PICCUR

• Parameter QUIET has been withdrawn. Instead set the MSG_FILTER environment variable to QUIET to suppress output messages.

PICTRANS

• Parameter QUIET has been withdrawn. Instead set the MSG_FILTER environment variable to QUIET to suppress display of the transformed positions.

PROVSHOW

• There is a new DOTFILE parameter that permits a summary of the provenance tree to be written to a text file in ``dot'' format, suitable for visualising with third-party tools such as GraphViz, ZGRViewer or OmniGraffle.

REGRID

• METHOD=GAUSS can now be used when re-sampling as well as when re-binning.

SCATTER

• The calculation of the axis ranges now excludes any pixels that are bad in either NDF.

SETAXIS

• If MODE is WCS and the selected axis is a celestial longitude or latitude axis, the axis units are now converted correctly from radians to degrees.

WCSMOSAIC

• Parameter ILEVEL has been withdrawn. Instead use the MSG_FILTER environment variable to control the output messages.

WCSTRAN

• Parameter QUIET has been withdrawn. Instead set the MSG_FILTER environment variable to QUIET to suppress display of the transformed positions.
• There is a new SKYDEG parameter that can be used to force celestial longitude and latitude axis values to be formatted as decimal degrees, regardless of the setting of the Format attributes for the axes.
