Aperture Photometry Tool, v. 2.6.7, Available Now!

Aperture Photometry Tool, v. 2.6.7, is now available:

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

There is an enhancement in this release.

After discussions with Dave Shupe, who now believes the linear and constant terms of the SIP distortion are indeed necessary, modified the code to use them. For images where this is important, APT now computes positions that more closely match DS9 when the WCS requires SIP-distortion corrections.

Aperture Photometry Tool, v. 2.6.6, Available Now!

Aperture Photometry Tool, v. 2.6.6, is now available:

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

There is an enhancement in this release.

Added the “cubehelix” color table for image display. Thanks to Dave Irey for this suggestion.

Aperture Photometry Tool, v. 2.6.5, Available Now!

Aperture Photometry Tool, v. 2.6.5, is now available:

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

There is an enhancement in this release.

Modified the “Export Photometry Data to CVS File” function under the File menu-bar category to optionally output one additional custom column, based on the FITS-header values associated with the images listed in the photometry-data file for a specified keyword. This is useful for time-domain astrometry, where it is desirable to have a JD or MJD column in the results table. Thanks to Stijn De Vusser for this suggestion.

Aperture Photometry Tool, v. 2.6.4, Available Now!

Aperture Photometry Tool, v. 2.6.4, is now available:

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

There is an enhancement in this release.

Added option to Preferences menu to choose between two different sizes of crosshair mouse cursor, regular (default) or large:

Preferences > Set Image-Display Attributes > Crosshair-Cursor Type

The crosshair cursor is seen when hovering over the main image-viewing panel. The large size is a customized version, and may not work under Mac OS X El Capitan.

Aperture Photometry Tool, v. 2.6.3, Available Now!

Aperture Photometry Tool, v. 2.6.3, is now available:

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

There is an enhancement in this release.

Modified the software to handle fpack-compressed FITS files with multiple image extensions. (The fpack-compressed FITS files have the .fz extension at the end of the filename.)

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).
