Version 8.028 released for Mira Pro x64.
May 18, 2018
For technical readers who simply must know: Here are
the results of our annual code analysis. Mira Pro x64 contains 1.8
million lines of source code authored in-house, plus much more from
licensed code libraries. The average code line length is 28 bytes.

Version 8.026 released for Mira Pro x64.
-
Added Open in Excel command to
measurement table menus. This copies the table contents directly to
Microsoft Excel rather than saving the table to a CSV file and
separately opening the file in Excel.
-
Added a Cosmic Ray Filter to
Cosmetic Corrections in the Express Calibration procedure. This filter remains
available separately in the Processing > Filters menu.
-
The local program help and on-line Web help were
greatly expanded.
January 24, 2018
Version 8.023 released for Mira Pro x64.
-
The new Adaptive Estimator photometric background estimation method
was implemented (see the January 16, 2018 announcement). This and
other background estimators are selected on the Other Properties page of the
Aperture Photometry Properties dialog.
-
Added Statistics measurements for data in Plot
Windows. Use the command in the Measure menu or the 's' keystroke
with the plot window being top-most. Statistics are chosen using the
Statistics Properties dialog. More than a dozen estimators are available.

New, robust photometric background estimation method
for Mira Pro x64.
-
A new Adaptive Estimator option for Mira Pro x64 solves a vexing
problem in aperture photometry for estimating the background level when stars and artifacts (e.g.,
cosmic ray events) contaminate the background ring around
the source. This new estimator can return an
accurate background estimate even when the background sample
contains artifacts significantly brighter than the target object.
One development goal for this estimator was to return an empirical
error, determined from the contaminated background sample in the
image data, approaching the theoretical error calculated from
internal sources (photon shot noise, readout noise, pixel response
non-uniformity, and digitization noise). This target was achieved
and the empirical error calculated from a contaminated background
sample now approaches a Gaussian Normal noise distribution with skewness near 0. This new estimator adds to
previous options including the mean, median, and mode.

Version 8.022 released for all 64-bit Mira platforms.
-
New Statistics Properties dialog for choosing
advanced statistics to be interactively measured using the image
cursor for one image or the image set.
-
New keystroke commands for Image Windows work
with the image cursor as accelerators for menu and toolbar commands
that measure a single image or image set:
a (align image set on centroid
position), c (centroid
coordinates), f (FWHM), h (horizontal plot),
i (pixel value
histogram), p (pixel value table), r
(radial profile plot), s (statistics; see
"Statistics Properties" item
above), v (vertical plot). These supplement
longstanding set of image window keystrokes, the arrow keys for
moving the image cursor and Tab/Alt+Tab for stepping forward or
backward through an image set.
-
Additional, detailed processing messages logged by the image
calibration pipeline functions.
-
New "Set Output Pixel Type" method added to the
Express Image Calibration pipeline.
-
Fixes to a few minor bugs.
Changes from version 8.022 back through version 8.003 are listed in the README document included in the installation.

December 22, 2017
Major update version 8.020 released for the
64-bit platforms
Mira Pro x64 and
Mira Pro.
This significant update includes many improvements and new
features, as shown in this
Mira Pro
x64 Screenshot. Here are a few:
-
Enhancements to the 6 pipelined image calibration commands,
including Create Master Bias, Create Master Dark, Create Master
Flat, Create Illumination Flat, Create Pixel Flat, and Express
Image Calibration. The master correction creation tools and Express
Calibration include options for 3 different bias methods and several
sub methods, 3 dark methods, 3 flat field types, 3 cosmetic
corrections, filtered flat libraries, and application of multiple
illumination flats.
-
New Chart module for
presentation graphics: The new chart window type takes data from measurements and other
tabulated data in table and view windows and panes. Charts may also be printed and copied as a
bitmap to the Windows clipboard for insertion into other documents.
Initially supported features include a variety of plot marker types
and properties, data grouping, legends, etc. The separate Plot
Window functionality continues to be available.
-
New Create Image Keyword List command: This new
tool
generates a table of images and values of their specified keywords. From the data
table, image sets may be created and column data may be plotted for
analytical purposes.
-
Speed improvements of tabulating photometry
measurements for large data sets.
-
Fixes to numerous small bugs present in minor
versions prior to this major release.
Changes from version 8.020 back through version 8.003 are listed in the README document included in the installation.

September 4, 2017
Release of 64-bit editions for
Mira Pro and
Mira AL.
A native 64-bit version is now available for Mira Pro and Mira AL,
in addition to continuation of the 32-bit versions for both. The 64-bit editions provide increased speed and virtually unlimited
64-bit memory space for working with huge images, huge image sets,
and huge image sets of huge images. The 64-bit editions require 64-bit
Windows. The 32-bit editions remain available for users who don't
need 64-bit capability or must install on 32-bit Windows. Otherwise, the 64-bit and 32-bit
editions have mostly similar features; see the detailed
feature comparison.
