CIAO 4.0 Release Notes

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

CIAO 4.0.2: Mac OS X 10.5 Intel

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.fits     
  

  This bug only affected users on Mac OS X Intel.
