Aperture Photometry Tool, v. 2.6.2, Available Now!

Aperture Photometry Tool, v. 2.6.2, is now available:

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

There is an enhancement in this release.

Modified the software to read in fpack-compressed FITS files directly, for images having a wider variety of BITPIX values. Only the first image extension is handled in this version (handling mulitple image extensions is deferred to a later version).

Aperture Photometry Tool, v. 2.6.1, Available Now!

Aperture Photometry Tool, v. 2.6.1, is now available:

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

There is an enhancement in this release.

Modified the software to read in fpack-compressed FITS files directly. Only the first image extension is handled in this version (mulitple image extensions to be handled in a later version). Thanks to Tom McGlynn (NASA/GSFC) for helping make this happen, and thanks to Edward Gomez (LCOGT) for pointing out the need for this new capability.

Aperture Photometry Tool, v. 2.6.0, Available Now!

Aperture Photometry Tool, v. 2.6.0, is now available:

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

There are enhancements and a bug fix in this release.

Added a new tool that computes the angular distance between two points on the sky, which is now available as the “Angular Distance Calculator” via the menu bar under the “Tools” menu.

Made source-code and tool-panel-layout improvements.

Bug fix: Modified the software to wrap around the negative values in the positive range when reading in FITS images with BITPIX=8. Thanks to Richard Kron for reporting this problem.

Aperture Photometry Tool, v. 2.5.9, Available Now!

Aperture Photometry Tool, v. 2.5.9, is now available:

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

There are enhancements in this release.

Performed source-code restructuring in some existing class files.

Added more bullet-proofing to the GUI of the source-list tool.

Added code to catch an ArrayIndexOutOfBoundsException that may occur when optionally median filtering the local non-annulus sky background for a grid size that is too large relative to the input image size.

Replaced the “Exit Preferences Menu” option with a “Close” button.

Modified the FITS reader to be robust against BZERO header lines with an extraneous zero at the line end. This is not FITS standard, and apparently is generated by MaxIm DL or ATIK-camera software. Thanks to James McNamara and Dario Castellano for reporting this problem.

Aperture Photometry Tool, v. 2.5.8, Available Now!

Aperture Photometry Tool, v. 2.5.8, is now available:

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

There are bug fixes and enhancements in this release.

Modified the FITS-image reader to be robust against cases where GAIN = ‘unavail’. Thanks to Lucimara Martins for reporting this problem.

Modified the code to write the entire input-image FITS header to the output FITS file containing the non-sky-annulus local background image from sky Model F (except for BZERO and BSCALE, which are seldom if ever used for a 32-bit floating-point image).

Aperture Photometry Tool, v. 2.5.7, Available Now!

Aperture Photometry Tool, v. 2.5.7, is now available:

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

There are bug fixes and enhancements in this release.

Bug fix: Eliminated the redundant header line in the output photometry file that occurs for automatic source-list processing when maximumNumThreads=1 (this was thought to be fixed in the previous version, but the fix was incomplete).

Added the capability of optional 3×3, 5×5, or 7×7 median filtering to coarse gridpoints in local non-annulus sky-background estimation (new user preference called “localNonAnnulusSkyBackgroundFilterType”).

Renamed (previously badly named) user preferences “localNonAnnulusSkyBackgroundSourceGridSize” and “localNonAnnulusSkyBackgroundSourceWindowSize” to simply “localNonAnnulusSkyBackgroundGridSize” and “localNonAnnulusSkyBackgroundWindowSize”, respectively.

Added new -b option to the batch-mode command, so that a non-default path and filename for the local non-annulus sky background can be specified.

Aperture Photometry Tool, v. 2.5.6, Available Now!

Aperture Photometry Tool, v. 2.5.6, is now available:

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

There are bug fixes and enhancements in this release.

Modified the source-list tool to keep the source numbering in the output photometry file consistent with the input source list for automatic source-list processing when maximumNumThreads=1 (this already has been implemented for maximumNumThreads>1). This change is necessary to handle cases where input sources may not be in the input image, even though the processing is input-list sequential for maximumNumThreads=1. Also, eliminated the redundant header line in the output photometry file that occurs for automatic source-list processing when maximumNumThreads=1. Thanks to Santiago Serrano for reporting these issues.

Added function getFluxFormatDescriptor to the FormatUtilities class to handle only formatting the flux and flux-uncertainty values written to the output photometry file (APT.tbl by default).

Aperture Photometry Tool, v. 2.5.5, Available Now!

Aperture Photometry Tool, v. 2.5.5, is now available:

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

There are bug fixes in this release.

Modified the software to catch a HeadlessException when getting the splash screen. Thanks to Santiago Serrano for apprising me of this problem.

Modified the non-scientific-notation format of the flux and flux uncertainty written to the output photometry file (APT.tbl by default) to always have 6 digits of precision. Thanks to Kym Hill for finding this problem.

Aperture Photometry Tool, v. 2.5.4, Available Now!

Aperture Photometry Tool, v. 2.5.4, is now available:

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

There is a Windows bug fix in this release.

Fixed a bug that was preventing the embedded images from being displayed in the software documentation included in the package (which is access via the “About & Help” button).

Aperture Photometry Tool, v. 2.5.3, Available Now!

Aperture Photometry Tool, v. 2.5.3, is now available:

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

There are bug fixes in this release.

Fixed a bug in the code that writes the non-sky-annulus local background image from sky Model F to a FITS file (needed to explicitly set BITPIX = -32).

Made it so the color-table panel is not displayed with running APT in the batch mode with the source-list tool.
