Starlink Software Collection - Kaulia Release Notes

You can download Kaulia from here.

General

SCUBA-2 raw data taken since February 2011 is now compressed. Kaulia is required in order to reduce new SCUBA-2 data.

A bug in FINDCLUMPS that could cause clump models creating by the GaussClumps method to have straight edges has been fixed.

General changes:
- A new graphical style attribute called TEXTMARGIN controls the width of margins cleared around the edges of each drawn text string.
- Applications that report pixel scales (e.g. NDFTRACE, WCSFRAME) now report more representative pixel scales using the median of several locations.
MFITTREND
- Permits processing of very large datasets by dividing into manageable sections.
SHOWQUAL
- Add new QNAMES output parameter to list the attribute name associated with each QUALITY bit.
WCSALIGN
- If an input NDF has more pixel axes than the reference NDF, an attempt will now be made to align the input using the reference axes, whilst retaining the other axes.

CALCQU - a new command to create Q and U values from SCUBA-2 fast-spinning polarimeter time series data files.
MAKECUBE
- Now allows the spatial reference pixel in the output cube to be specified by the user.
- Setting TRIM=YES now modifies any user-supplied LBND/UBND values to remove borders of bad pixels.
MAKEMAP
- The loading and flatfielding of raw data on multi-core systems is now faster.
- The focal plane distortion model has been updated to cover the entire focal plane.
- A new parameter (TRIM) has been added to allow borders of blank pixels to be removed from the output map.
- A bug has been fixed so that a request to perform just one iteration (numiter=1) is honoured.

The FitsChan class (used by most Starlink applications to read and write WCS information as FITS headers) now includes support for CTYPE values that use the "-TAB" algorithm code.
The graphics module interface (grf) used by AST has been extended to include two new functions that control the buffering of graphical output produced by Plot methods.
The KeyMap class has a new attribute that can be set to zero to make the handling of keys case insensitive.
The Region class has a new method that returns a set of positions covering the boundary, or volume, of a supplied Region.

A new graphical attribute called "TextMargin" can be used to specify the width of a margin to clear around each plotted text string.

The structure used to hold Provenance information has been changed. It now occupies much less disk space and is much faster to read and write. Older starlink releases will ignore such re-structured provenance information.
