New
features in version 2.0.36
This
version of C2A is compatible with the realease 1.5 of the C2A
Add-In for Occult Watcher, i.e. you must get version 2.0.36
of C2A when using the Occult Watcher C2A Add-In 1.5.
It
is now possible to use 2MASS magnitudes for the display of the UCAC3
catalog.
The
UCAC3 flags are used to determine how stras from this catalog
are displayed in the maps:
- If the flag "object could be from possible streak"
is set, the star is displayed with a blue circle.
- If the star is overexposed on one or several frames or if it is
close to an overexposed star, it is displayed with a red circle.
- If the star has a "meanclass" flag which is not
set to "star", it is displayed using the white color.
In all other cases, UCAC3 stars are displayed with the default star
color.
The
default color for the pre-pointing marks has been changed.
A
problem has been fixed in the english version of the Reset.exe
utility. The registry key was not correctly deleted when requested.
The version 2.5 of the Reset.exe utility has been released.
It
is now possible to only download a C2A update without having to get
the full version with all the catalogs (see above). |

In order to install the C2A for Windows distribution on your system,
extract the contents of the ZIP archive in a temporary directory
and run the setup.exe executable. Then simply follow the
installation steps as displayed on the screen. Please
be aware that the Windows installation procedure (but nor the software
itself)
is in French, which should not be a problem considering it is a
very basic installation.
If
a version of C2A older than 2.0.35 is already installed
on your system, uninstall it first using the Windows Configuration
Panel. Then install the new version. Your settings will not be lost.
If
a version more recent than 2.0.35 is installed
on your system, you do not have to uninstall it prior to the install
of the new version. The new install will override the old one. |

Occult
Watcher is a software designed to easily manage predictions
of star occultation by asteroids. An Add-in is available to directly
launch C2A from Occult Watcher and display a map of the occultation
(setting automatically the time, location and catalogue for the
considered event). The Hipparcos and UCAC2 catalogues are often
used in occultation predictions, so it is necessary to have them
installed on your computer before using this Add-in. See the Catalogues
page to download the Hipparcos catalogue and the Tools
page to get the UCAC2 catalogue compiler for C2A.
Caution!
In order to use this C2A Add-in for Occult Watcher, you need at
least version 2.0.36 of C2A and the most recent
version of Occult Watcher.
To
install the Add-in, simply extract the file OccultWatcher.C2a.dll
(available in the ZIP file) and copy it into the Occult Watcher
installation folder. A C2A entry will then be added in the Occult
Watcher Add-in menu. To launch C2A and get the map of an event,
select this event in the Occult Watcher list and go into the "Add-in"
menu to create the C2A Occultation Map.
New
features in version 1.5 are the following:
The new default
C2A installation path is taken into account (C:\Program Files\C2A).
It is now possible to select the catalog to be displayed by C2A
when creating a map from Occult Watcher. |
