Aperture Photometry Tool, v. 2.4.9, Available Now!

Aperture Photometry Tool, v. 2.4.9, is now available:

http://www.aperturephotometry.org/aptool/download/

There are minor bug fixes and enhancements in this release.

Fixed quantization errors in data-to-color assignments for the displayed image.

Augmented the software with the new capabiliby of zooming in on the image displayed on the main GUI panel.

Added package statements to all Java source-code files (finally!).

Developed an ant build script to streamline building and packaging.

Modified the scroll-bar policy to have the scrolls bars always appear.

Added a custom crosshair cursor, so that the cursor’s hot spot can be fine-tuned (works on Macs only).

Added a new “Find Aperture” button to reposition the image scroll bars so that the overlaid source is centered.

Modified the software to propapgate the (R.A., Dec.) of the aperture to the constructor of the “Position Locator” panel.

Fixed an indexing bug in the image exporter that was causing a single row and column of pixels through the image center to be skipped.

Aperture Photometry Tool, v. 2.4.7, Available Now!

Aperture Photometry Tool, v. 2.4.7, is now available:

http://www.aperturephotometry.org/aptool/download/

There are bug fixes in this release.

Minor bug fix: On the “Export Photometry to CSV File…” panel, grayed out the “Include FITS header in CSV File?” checkbox if an image is not open.

Minor bug fix: In the main class, eliminated many unnecessary class attributes by localizing their scope.

Solved the long-standing annoying Mac behavior of resultant grayed-out menu-bar items after changing certain settings in the “Preferences” menu.

Aperture Photometry Tool, v. 2.4.6, Available Now!

Aperture Photometry Tool, v. 2.4.6, is now available:

http://www.aperturephotometry.org/aptool/download/

There are enhancements in this release.

Added one more digit of precision to the decimal representation of (RA, Dec), in order to accommodate projects with high astrometric accuracy.

Modified the software to explicitly load an aperture correction of unity when “Manually Set Aperture Correction” is the aperture-correction mode selected in the user preferences.

Aperture Photometry Tool, v. 2.4.5, Available Now!

Aperture Photometry Tool, v. 2.4.5, is now available:

http://www.aperturephotometry.org/aptool/download/

There are enhancements and bug fixes in this release.

Increased the maximum allowed aperture radius from 200 to 1000 (you have to key in the larger value into the text fields, as the sliders encourage values less than or equal to 200). Large apertures compute very slowly (this part is not yet multi-threaded), and the software appears to hang. But if you are patient and wait long enough, the computation will finish and return control to the GUI. You can speed it up somewhat by selecting the largest calculation step size in the Preferences menu.

Minor bug fix: Added function call to make the “Recompute Photometry” button’s text turn the color red when “Aperture-Correction Mode” in the Preferences menu is selected.

Bug fix: The default source-list filename failed to load into the “Source-List Tool” panel when “Enable Automatic Source-List Creation With Inputs From Saved Preferences or Default Values” in the Preferences menu is selected, and the option to compute the aperture corrections now is selected — this thread-concurrency problem is now fixed.

Aperture Photometry Tool, v. 2.4.4, Available Now!

Aperture Photometry Tool, v. 2.4.4, is now available:

http://www.aperturephotometry.org/aptool/download/

There are minor bug fixes in this release.

Minor bug fix: Modified the software to be able to read in real keyword values that are enclosed in single quotes.

Minor bug fix: Modified the position-locator tool to load the image of the located aperture position into the elliptical-aperture-attributes panel, so that the located position can be visualized there for purposes of aperture resizing and reshaping.

Aperture Photometry Tool, v. 2.4.2, Available Now!

Aperture Photometry Tool, v. 2.4.2, is now available:

http://www.aperturephotometry.org/aptool/download/

There is an enhancement in this release.

Modified the FITS-image reader to handle FITS images with no white space between keyword values and forward slash of keyword comment. Thus, the software now handles FITS files with world-coordinate systems generated by SBIG’s CCDSoft program. Thanks to Adam Rengstorf for bringing this to light.

Aperture Photometry Tool, v. 2.4.1, Available Now!

Aperture Photometry Tool, v. 2.4.1, is now available:

http://www.aperturephotometry.org/aptool/download/

There is a minor bug fix in this release.

Minor bug fix: Added the input parameters for source-list creation to the subroutine that initializes the installed default values, which was preventing source-list creation in the batch mode when preferences were not saved. Thanks to Oliver King for finding this problem.

Aperture Photometry Tool, v. 2.4.0, Available Now!

Aperture Photometry Tool, v. 2.4.0, is now available:

http://www.aperturephotometry.org/aptool/download/

There are enhancements and a minor bug fix in this release.

Added a check box to the “Source-List Tool” panel to optionally overlay small circles on the image in the main image-viewing panel that correspond to source-list positions. Also, added a user-preferences option under “Set Image-Display Attributes > Overlay Color” to change the overlay color; the default overlay color is green. The source overlays will be displayed as long as the “Source-List Tool” panel has not been either reopened with the “Source List” button or closed with the “Close Window” button and the aforementioned box is checked.

Minor bug fix: Updated APT.csh and APT.bat to handle up to 10 input arguments for full batch-mode control (this was an oversight in the previous version).

Aperture Photometry Tool, v. 2.3.9, Available Now!

Aperture Photometry Tool, v. 2.3.9, is now available:

http://www.aperturephotometry.org/aptool/download/

There are enhancements in this release.

Modified the ApertureCorrections class to use the local non-annulus-based background image computed from modal values, instead of median values.

Cleaned up some obsolete code in the ImageCalculator class.

Added new “-p” command-line option to the available options, which is for specifying a user-preferences filename for the APT session:

APT.csh -i input_FITS-image_filename
        -p user_preferences_filename
        -s input_source_list_filename or "sourceListByAPT" for automatic source-list creation
        -o output_aperture-photometry-table_filename
        -z zero_point
        -h (help switch for available command-line options)

Added logic to limit the window size of the local-statistics calculations to be no bigger than half the smallest image dimension.

Modified the software to include the width and height of the main GUI as user preferences. Thanks to Dave Irey for this suggestion.

Added an option to the “Export Photometry Data to CSV File” tool to write the FITS-header keywords and values to the header of the output photometry-data table.

Aperture Photometry Tool, v. 2.3.8, Available Now!

Aperture Photometry Tool, v. 2.3.8, is now available:

http://www.aperturephotometry.org/aptool/download/

There are enhancements and minor bug fixes in this release.

Added an option to the “Export Photometry Data to CSV File” tool to write the user preferences to the header of the photometry-data table.

Modified the “Sky Annulus” button on the “Elliptical-Aperture Attributes” panel to be disabled when the “Photometry Major Radii” panel is open. Similarly, modified the aperture-attributes button on the “Photometry Major Radii” panel to be disabled when the “Elliptical-Aperture Attributes” panel is open.

Added an “Export Contents” button to the “Photometry File” panel.

Minor bug fixes: Disallow more than one instance of the panel that lists the user preferences (affects Macs only). Ditto for the “Export Photometry Data to CSV File” panel.
