CIAO 4.0.2 Release Notes
![[New]](../imgs/new.gif)
(16 Apr 2008) CIAO 4.0 has been
patched to CIAO 4.0.2 on Mac OS X Intel only. The patch
should not be applied to Linux, Solaris, or Mac PowerPC
installations of CIAO.
In addition to the patch, there is an updated standalone version of ObsVis for Mac OS X Intel; see the ObsVis website for details and the download.
Mac OS X platforms: FITS table file writing slowness with NFS-mounted disks.
FITS table file writing through the CXC Data Model slows by a significant factor on Mac OS X machines - both 10.4 (Tiger) and 10.5 (Leopard) - when the data is accessed via a networked file system (NFS) mount. This issue does not affect Solaris or Linux platforms.
CIAO 4.0.2: Mac OS X 10.5 Intel
The CIAO 4.0.2 patch enables CIAO to run on Mac OS X 10.5 (Leopard) Intel. The patch file may be applied to CIAO 4.0 or 4.0.1.
The patch is optional for Mac OS X 10.4 (Tiger) Intel machines. Users who choose to install it will get updated versions of ds9 and XPA, as well as a fix to the Data Model.
We currently do not support CIAO on Mac OS X 10.5 (Leopard) PowerPC. Please contact the CXC Helpdesk if you are interested in having this version of CIAO available.
User Interface
-
The 10.5 Intel release includes the Leopard ports of ds9 v5.1 and XPA v2.1.9, along with several updates to the UI applications ChIPS and Prism.
Data Model
-
NaN values were not being recognized as such; they were instead handled as very small numbers (1.06x10^-314). This example is a case where the bug may have been seen:
unxi% dmcopy infile=file.fits"[bin (#1,#2)=2][(#1,#2)=circle(25,25,25)][opt null=nan]" \ outfile=filtered.fitsThis bug only affected users on Mac OS X Intel.
