Bugs: ds9, dax, and XPA


A list of bugs fixed in CIAO 4.2 is available.


Caveats

  1. ximtool: inet port 5137 already in use - disabled (15 Dec 2008)

Bugs

  1. Accessing specific extensions in FITS region files is broken in ds9 v5.6.1 (30 Apr 2009)


Caveats

  1. ximtool: inet port 5137 already in use - disabled (15 Dec 2008)

    When running more than one ds9 from CIAO simultaneously, every instance after the first results in this message:

    ximtool: inet port 5137 already in use - disabled
    

    The first instance of ds9 opened socket 5137 in xpans, so the subsequent instances of ds9 cannot create another 5137 socket.


Bugs

  1. Accessing specific extensions in FITS region files is broken in ds9 v5.6.1 (30 Apr 2009)

    The version of ds9 packaged with CIAO, ds9 v5.6.1, can only access the first extension (block) in a FITS region file.

    This will primarily affect users working with the output of vtpdetect and the CSC L3 region files.

    Workarounds:

    1. Use dmcopy to copy the desired block from the file:

      unix% dmlist vtp_out.fits blocks
      
      --------------------------------------------------------------------------------
      Dataset: vtp_out.fits
      --------------------------------------------------------------------------------
      
           Block Name                          Type         Dimensions
      --------------------------------------------------------------------------------
      Block    1: PRIMARY                        Null
      Block    2: SRCLIST                        Table        24 cols x 601      rows
      Block    3: SRC_REGION                     Table         5 cols x 658      rows
      
      unix% dmcopy "vtp_out.fits[3]" SRC_REGION.fits
      
      unix% dmlist SRC_REGION.fits blocks
      
      --------------------------------------------------------------------------------
      Dataset: SRC_REGION.fits
      --------------------------------------------------------------------------------
      
           Block Name                          Type         Dimensions
      --------------------------------------------------------------------------------
      Block    1: PRIMARY                        Null
      Block    2: SRC_REGION                     Table         5 cols x 658      rows
      
    2. Download a newer version (6.5.3 or higher) of ds9 from the ds9 website.


Bugs fixed in CIAO 4.2

The following is a list of bugs that were fixed in the CIAO 4.2 software release.

  1. dax plots total lightcurve counts even when background is supplied (06 Oct 2009)

    When both source and background regions are defined, dax uses both in dmextract to compute the net counts. This is done correctly.

    When the result is plotted in lightcurve mode (i.e. CIAO → Histograms → TIME ), however, the count_rate column is plotted instead of the net_rate.
