Aperture Photometry Tool, v. 2.6.9, Available Now!

Aperture Photometry Tool, v. 2.6.9, is now available:

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

There is a bug fix in this release.

Fixed the code that auto-detects a header line in the source list, which was not working because of a subsequent switch to a different token-reader function that does not generate an InputMismatchException where the auto-detection was previously handled.

Aperture Photometry Tool, v. 2.6.8, Available Now!

Aperture Photometry Tool, v. 2.6.8, is now available:

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

There is an enhancement in this release.

Upgraded the software to handle images with CTYPE1 = ‘RA—TPV’ and CTYPE2 = ‘DEC–TPV’ specified for the world-coordinate system.

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.
