Aperture Photometry Tool, v. 2.8.3, Available Now!

Aperture Photometry Tool, v. 2.8.3, is now available:

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

There are enhancements in this release.

Made modifications to break the code dependence on com.apple.eawt.* classes when APT is executed on a Mac via the APT.csh script. Under these conditions (i.e., execution of APT via APT.csh or directly via java command from terminal window), the Apple Legacy Java 6 is no longer required, and APT can be executed under higher Java versions (which are bereft of the com.apple.eawt.* classes). Without the com.apple.eawt.* classes, the famous Apple menu bar at the top of the screen cannot be programmed in Java, and, therefore, it has been set to “IGNORE” (this cannot be simply turned off). The APT menu now always resides at the top of the frame of APT’s main GUI panel, regardless of whether the machine runs Mac OS X (or macOS), Windows, or Linux. APT will still run as a Mac double-click application provided that Apple Legacy Java 6 is installed, but now it can also be run on a Mac from a terminal window under a higher Java version.

Added function printEnvironmentToFile to main-class APT, which generates a dump of the system properties and environment to a file called env.txt in the hidden directory each time APT is started up.

Replaced test System.getProperty( “os.name” ).contains( “OS X” ) with new APT.isMac() function (to contain the OS-detection functionality).

Added new user preference magnifierDefaultMagnificationLevel, which is allowed to be assigned any of the following values: 5, 10, 20. Added option to Preferences menu to set this value, called “Set Default Magnifier Magnification”.

Improved the display of the “About & Help” documentation.

Modified script APT.nsi to skip check of JRE version; the Windows double-click APT launcher, APT.exe (which is included with APT_vX.Y.zip), is generated by compiling this script. Also, increased the Java memory allocation in APT.nsi (and therefore APT.exe) from 1024M to 4096M.

Aperture Photometry Tool, v. 2.8.2, Available Now!

Aperture Photometry Tool, v. 2.8.2, is now available:

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

There are enhancements in this release.

Upgraded the Simple Photometric Calibration Tool to allow either decimal or sexagesimal coordinates in the input lists.

Added a -v command-line option to allow users to control the verbosity of the standard output (adding the associated code logic in all the needed places is a work in progress):

APT.csh or APT.bat, v. 2.8.2

Interactive-Mode: Refrain from using both -i and -s options below together.

Batch-Mode: Use both -i and -s options below together; other available options can also be used.

Command-Line Options Available:
 -i input FITS-image filename
 -p user_preferences filename
 -s input_source_list_filename or "sourceListByAPT" for automatic source-list creation
 -o output aperture-photometry-table filename
 -b output local_non-annulus_sky_background filename; always computed, but applied only when Model F (noSkyFlag=5) is specified
 -z calibrated image magnitude zero point
 -v verbosity level; default is zero; 0 or 1 is currently recognized

Thanks to Paul Leyland for these suggestions.

Aperture Photometry Tool, v. 2.8.1, Available Now!

Aperture Photometry Tool, v. 2.8.1, is now available:

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

There is a bug fix in this release.

Fixed a sign-error bug when converting sexagesimal values that lie in the (-1, 0) range into decimal values. Thanks to Paul Leyland for reporting this problem.

Aperture Photometry Tool, v. 2.8.0, Available Now!

Aperture Photometry Tool, v. 2.8.0, is now available:

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

There is a bug fix in this release.

Added logic to function processHeaderCard in the ReadFitsFile class, in order to fix a bug that prevents loading an image from the multi-extension HST-WFPC file w0ji2201t_c0f.fits. Thanks to Richard Nowell (Bristol U.K.) for reporting this issue.

Aperture Photometry Tool, v. 2.7.9, Available Now!

Aperture Photometry Tool, v. 2.7.9, is now available:

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

There is a bug fix in this release.

Added logic to better detect HDUs containing image data in FITS files. Thanks to Paul Leyland for reporting this issue.

Aperture Photometry Tool, v. 2.7.8, Available Now!

Aperture Photometry Tool, v. 2.7.8, is now available:

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

There is a bug fix and enhancements in this release.

Bug fix: Forgot to divide output attribute ApertureNumRejected by the square of the calculational step size. Recast ApertureNumRejected from integer to double, in order to track fractional pixels.

Interface-change warning: There is a new column included in the output photometry-table file, called Flags, which is an integer that contains bit-wise binary flags for various conditions that affect the results.

 Aperture-Photometry-Tool Flags

 Bit   Value   Condition
 --------------------------------------------------------
  0       1     Aperture contains one or more source pixels (or portions thereof)
                with non-NaN values that were rejected from the
                photometry calculation (i.e., outside of range defined by
                lowerSrcDataLimit and upperSrcDataLimit in APT.pref).
  1       2     Aperture contains one or more source pixels (or portions thereof)
                with blanks or NaNs (not a number).
  2       4     Aperture contains one or more source pixels (or portions thereof)
                with values at or above the saturation level
                (caveat emptor: pixels in the original image might have been zapped,
                in which case, these are not included here).

Note: If either of the interpolation source algorithms is selected (Model 1 or 2),
      then the flags for bits 0-2 will apply to the interpolated values that
      replace original values.

Thanks to Paul Leyland for suggestions that lead to this improvement.

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!

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:
