Aperture Photometry Tool, v. 2.7.3, Available Now!

Aperture Photometry Tool, v. 2.7.3, is now available:

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

There are enhancements and bug fixes in this release.

Modified the ReadFitsFile class to more generally handle the parsing of multi-extension FITS files that include admixtures of IMAGE and TABLE header-data units (HDUs). Modified the HDU class to add XTENSION and ZTENSION as attributes. Added error checking for the case where a FITS file has no image HDUs.

Increased the default Java heap-space size allocated for APT start up from 1024 to 2048 megabytes, so that APT can load images as large as 10Kx10K pixels.

Completely overhauled the Pick/Zap Tool, in order to dramatically improved its responsiveness. Changed the default pick color from blue to cyan to differentiate it from the default blank color.

Sorted out a bug that prevented the photometry-file table header from being written when individual photometry records are saved. Thanks to Roc Cutri for apprising me of this problem.

Aperture Photometry Tool, v. 2.7.2, Available Now!

Aperture Photometry Tool, v. 2.7.2, is now available:

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

Added “Peak pixel (X, Y, value)” to the display of quantities in the “APERTURE MEASUREMENTS” box on the main GUI panel. Thanks to Jim DeYoung for this suggestion.

Modified the ReadFitsFile class to more generally handle the parsing of multi-extension FITS files.

Aperture Photometry Tool, v. 2.7.1, Available Now!

Aperture Photometry Tool, v. 2.7.1, is now available:

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

Improvement to function that exports photometry data to a CSV file: Write a hash character (#) at beginning of lines for preferences and header keyword/value pairs, in order to signal file parsers ignore them as comment lines.

Speeded up the function that exports photometry data to a CSV file, and also substantially reduced its memory requirements.

Added capability of setting up APT preferences to automatically generate a CSV photometry file with time tags from a FITS-header keyword, such as OBSMJD, when executing source-list processing in the batch mode. Thanks to Dr. Giuseppe Leto of the INAF – Osservatorio Astrofisico di Catania for this suggestion.

Aperture Photometry Tool, v. 2.7.0, Available Now!

Aperture Photometry Tool, v. 2.7.0, is now available:

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

Changed the default blank and saturated pixel colors for the cubehelix color table to the same used for the gray-scale image display (bright blue and bright red, respectively).

Did restructuring of the PixelAttributes classes for efficiency, consistency, and readability.

Modified the code to allow fpack-compressed FITS files with multiple image extensions to be read in as comparator images. (The fpack-compressed FITS files have the .fz extension at the end of the filename.) Thanks to Sarah Eve Roberts for raising this issue.

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.
