Version History

  • 5.0 - 10/7/07 - few tweaks including a coffeecup cursor, and some clarification of names of throughputs
  • 5.0b - 9/7/07 - Added a JCheckBox to set up default HST counts.
    - Default HST counts use new completeness function from Scoville et al.
    - flashing on and off is fixed.
  • 4.2 - 31/5/07 - Added HST F450W, F606W and F814W bands with a single number conversion to B,R,I
    - conversions are fromfrom Metcalfe et al. 2001, based on median HDF galaxy colours with F814W<28.
  • 4.1 - 6/3/07 - Changed calculation of variance.
    - Previous versions used an analytic calculation that assumed a continuous distribution of galaxies,
    - we now use numerical methods which assume a discrete distribution, as in Peebles 1975, eqn. 10.
    - Non-poissonian variance is approximately 25% higher in the new version.
    - We now also allow different window functions to be used.
    - The default sigmoid function has been changed from a slope of 1.4 to a slope of 3.0
  • 3.1 - 08/11/06 - Completeness limits from SDF converted to Vega mags.
    - Completeness exposures from SDF corrected (before assumed all = 595 minutes)
  • 3.0 - (not released) - Significant changes in the following:
    - previously the non-Poissonian part of the variance was wrong by a factor (4-delta)
    - now assumes a square cell instead of a circular cell.
    - also made language change replacing deprecated .show() with .setVisible(true)
    - fixed truncated title with ipadx=100
  • 2.2 - 3/4/06 - Bug fixed in scaling completeness with SNR - was working in wrong direction
  • 2.1 - 10/3/06 - Bug fixed in which the window was not redrawn on Linux.
  • 2.0 - 27/2/06 - Release number 2.0 signifies the astro-ph release.
  • 1.6 - 27/2/06 - Enlarged JComboBox magbox to show all filters at once.
  • 1.5 - 24/2/06 - Variable throughputs added. Completeness tab added showing sigmoid and completeness limits.
  • 1.4 - 22/2/06 - Cosmetic changes including a help button for throughput
  • 1.3 - 13/2/06 - Axes improved in DrawGraph and AwDrawGraph
  • 1.2 - 8/2/06 - Bug fixed - input own value now works again
  • 1.1 - Test release. ugriz conversions use Bruzual and Charlot z=0 colours.
