Tangra 1.2 Released
Existing users can update by choosing Help -> Check for Updates from the
menu and new users can install the software following the instructions on http://www.hristopavlov.net/Tangra/publish.htm
The majority of the changes are related to astrometry but there are also the
following improvements in the occultation light curve reduction space:
Added a new 'Field Rotation' flag which should prevent the
measurement
tracking from failing due to large field rotation in videos recorded with Alt-Az
mounted telescopes
Now the light curves viewing form allows you to choose the
normalisation
method when normalising a light curve. The supported methods are: 4 point
average, 16 point average, point for point and linear fit
An Excel file export issue with added extra white spaces has been
fixed
The message shown by Tangra when the time duration derived from
the
timestamps entered by the user differs from the duration computed from the video
frame rate will now also include the computed frame rate, not just the time
difference
A couple of rare crashes caused mostly by the different rendering
engines have been fixed
Changes to the Light Curve Reduction:
- A few minor bugs around selection of targets have been fixed
- Now the background annulus is displayed for the selected target in the zoomed area
Changes to Astrometry:
-Added an automatic levels adjustment to darken the background level
Others:
-Now Tangra's functionality can be extended by implementing add-ins. Download the Software Development Kit (SDK) from Tangra's web site
-The auto-update process now works better with User Access Control (UAC) on Windows Vista and Windows 7作者:
