Starlink Software Collection - Hawaiki Release Notes

This page is a work in progress containing the changes that will be in the hawaiki release

General

All Starlink command-line applications now support message filtering using the MSG_FILTER and QUIET parameters. The QUIET parameter can always be used to disable message output from a command. MSG_FILTER can take strings values of "NONE", "QUIET", "NORM", "VERBOSE", "DEBUG", "DEBUG1" to "DEBUG20" and "ALL. Applications that used an ILEVEL parameter now use MSG_FILTER (KAPPA, CUPID and POLPACK). The MSG_FILTER environment variable can be set to one of these values to globally control message output.
This is the first release that officially supports SCUBA-2 data processing.

The dimensionality restriction on BLOCK has been removed. As a consequence the AXES parameter is withdrawn.
The ILEVEL parameter used by FFCLEAN, MSTATS and WCSMOSAIC has been replaced with MSG_FILTER.
FITSLIST has 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.
NDFCOPY has a new COMP parameter that permits the QUALITY or VARIANCE component to become the DATA_ARRAY in the output NDF.
SETAXIS now correctly sets the AXIS units to degrees when the selected axis is a celestial longitude or latitude axis. Previously reported radians.
PROVSHOW can now write the provenance information to a "dot" format file suitable for visualization by tools such as GraphViz or OmniGraffle.
WCSTRAN has a new SKYDEG parameter to force a celestial longitude and latitude to be formatted as decimal degrees.
REGIONMASK can now determine the 2-d plane to mask by matching the region to the N-d frameset.
No longer report an error if there are too few points for ordered statistics. The median will be set to the bad value.

First official release supporting SCUBA-2 raw data (rather than simulated data).
New command CALCNOISE for calculating the noise properties of a SCUBA-2 observation.
New command COPYFLAT to copy a flatfield from one SCUBA-2 observation to another.
New command STACKFRAMES for taking a collection of 2d images (eg noise images or responsivities) and placing them into a time series cube.
SC2FFT will now concatenate all related files before calculating the FFT.
MAKECUBE can now avoid generating very thin tiles when tiling is enabled.
JCMTSTATE2CAT now calculate DRA and DDEC columns to indicate arcsecond offsets from base position. Additionally DAZ and DEL are now given as offsets from BASE rather than offsets from the first base position.
For SCUBA-2 files JCMTSTATE2CAT will now include MCE header information and will calculate the tau dynamically from the raw WVM data.

Message filtering will now look at both the MSG_FILTER and QUIET parameters in addition to the MSG_FILTER environment variable.
!msgIfget no longer takes an argument describing the name of the ADAM parameter.
New routine !msgIfgetenv to read the message filtering level from the environment.
!msgIflev now returns a string representation of the current message filter level.
MSG_FLEVOK is now part of the Fortran interface.

"%" can now be used to indicate a percentage of the data array in an NDF section.
Add a new frame FRACTION providing normalised pixel coordinates that are guaranteed to use the range 0.0 to 1.0.
Add AUTO_HISTORY environment variable. If set and true, history will be written to all NDFs created.

The IFL parser now includes two new parameters (MSG_FILTER and QUIET) if they have not previously been defined in the IFL file.
Message filtering is now enabled in the fixed ADAM part to allow all applications to benefit from a unified API.
