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.

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.

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!

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.
