Starlink Software Collection - Namaka Release Notes
this page is a work in progress used to hold the release notes as work on namaka proceeds
General
- Major updates to SMURF to support SCUBA-2 data processing
- The MAG library has been removed along with the routines in KAPPA and TSP that used them.
- We have fixed the Starlink URLs so that www.starlink.ac.uk, star-www.rl.ac.uk and www.starlink.rl.ac.uk all point to JAC.
New Applications
Changes to Applications
Convert
- FITS2NDF
- Some fixes to the handling of UKIRT CGS4 data from the UKIRT archive at CASU (which are in FITS format).
CURSA
- Now works with bash shell.
Figaro
- Fixed initialisation bug in ARC2D that prevented editing of the spectral-line table.
KAPPA
- LISTSHOW
- A new Parameter STEP has been added that allows a subset of the positions identifiers between FIRST and LAST to be displayed.
- MAKESURFACE
- Output variances can now be created for spline fits.
- PSF
- A bug has fixed in the normalisation of the fit in cases where both the NORM and GAUSS parameters are set FALSE.
- WCSSLIDE
- A bug has been fixed that could lead to incorrect shifts when using the ABS parameter.
SMURF
- SC2CLEAN
- The parameter DCBOX has been renamed DCFITBOX.
- DCBAD and DCFLAGALL parameters have been removed.
Changes to Libraries
AST
The KeyMap class has a new method called astMapCopy/AST_MAPCOPY that copies entries from one KeyMap to another KeyMap.
The KeyMap class now supports entries that have undefined values. A new method called astMapPutU/AST_MAPPUTU will store an entry with undefined value in a keymap.
The KeyMap class has a new boolean attribute called MapLocked. If true (non-zero), an error is reported if an attempt is made to add any new entries to a KeyMap (the value associated with any old entry may still be changed without error). The default is false (zero).
- The Object class has a new method called astHasAttribute/AST_HASATTRIBUTE that returns a boolean value indicating if a specified Object has a named attribute.
The SkyFrame class has two new read-only boolean attributes called IsLatAxis and IsLonAxis that can be used to determine the nature of a specified SkyFrame axis.
- A bug has been fixed in the astRebin(Seq)/AST_REBIN(SEQ) methods that could cause flux to be lost from the edges of the supplied array.
- A bug has been fixed in the astRebin(Seq)/AST_REBIN(SEQ) methods that caused the first user supplied parameter to be interpreted as the full width of the spreading kernel, rather than the half-width.
The StcsChan class now ignores case when reading STC-S phrases (except that units strings are still case sensitive).
The Channel class now has an Indent attribute that controls indentation in the text created by astWrite/AST_WRITE. The StcsIndent and XmlIndent attributes have been removed.
All classes of Channel now use the string "<bad>" to represent the floating point value ASTBAD, rather than the literal formatted value (typically "-1.79769313486232e+308" ).
The KeyMap class now uses the string "<bad>" to represent the floating point value ASTBAD, rather than the literal formatted value (typically "-1.79769313486232e+308" ).
The KeyMap class has a new method called astMapPutElem<X>/AST_MAPPUTELEM<X> that allows a value to be put into a single element of a vector entry in a KeyMap. The vector entry is extended automatically to hold the new element if required.
- The DSBSpecFrame class now reports an error if the local oscillator frequency is less than the absoliute value of the intermediate frequency.
- A new method astQuadApprox produces a quadratic fit to a 2D Mapping.
A new method astSkyOffsetMap produces a Mapping from absolute SkyFrame coordinates to offset SkyFrame coordinates.
ATL
- Add ATL_ADDWCSAXIS for adding a new independent axis to an existing frameset.
Add ATL_PTFTD to put a double precision value into a FitsChan
- Remove ATL_MAPCOPY since this functionality is now present in AST directly.
KAPLIBS
- New routine (kpg1Config) for reading a configuration file and merging the contents with defaults.
Config files can now include "<def>" to revert to the default value.
Config files can now include "<undef>" to store an undefined value using kpy1Kymap.
- Removed support for FITS tapes.
NDG
- C interface added for NDG_ADDGH
- Now uses PSX_WORDEXP rather than ONE_SHELL_ECHO and ONE_FIND_FILE.
- Some fixes to the provenance code to determine whether an ancestor refers to the same file.
PSX
- The new routine PSX_WORDEXP has been added to provide a wrapper around the POSIX wordexp() function. This allows strings to be expanded with environment variables and wildcards without forking a new shell.
