Aperture Photometry Tool, v. 2.7.7, Available Now!

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

There is a bug fix in this release.

Bug fix: Modified the WCS class to apply the PC matrix in fixing a CDELT1 sign error, which is needed for Pan-STARRS images. Thanks to Richard Nowell (Bristol U.K.) for pointing out this problem.

Aperture Photometry Tool, v. 2.7.6, Available Now!

Aperture Photometry Tool, v. 2.7.6, is now available:

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

There is an enhancement in this release.

Modified APT to check whether the to-be-loaded FITS image is compressed (regardless of filename extension). The allows the software to load Pan-STARRS images, which are compressed, but do not have the .fz filename extension. Thanks to Rick Nowell for raising this issue.

Aperture Photometry Tool, v. 2.7.5, Available Now!

Aperture Photometry Tool, v. 2.7.5, is now available:

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

There is a bug fix in this release.

Fixed bug in PrimaryImageFilter.java that prevents *.fts images from being loaded.

Aperture Photometry Tool, v. 2.7.4, Available Now!

Aperture Photometry Tool, v. 2.7.4, is now available:

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

There are enhancements in this release.

Forgot to increase -Xmx1024m to -Xmx2048m in the Info.plist file used for the double-click Mac application, which is normally installed in the /Applications folder (see related upgrade in the revision history for the previous version of APT below).

Increased the default maximum image size from 5Kx5K pixels to 10Kx10K pixels. It takes a minute or so to load an image this large, so be patient!

Modified the code that loads a FITS image to allow FIT and FTS (all letter-case permeatations) as FITS-filename extensions, in addition to FITS and FZ. Thanks to Jim DeYoung for this refinement.

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.
