Cheddar is the special expert's tool for preparation of MIDI (and maybe other VLTI) observations. It shows elevation, position angle and length of the projected baseline for a list of targets during one night.
All you need is a computer with tcl/tk installed and this tarball (Cheddar version 2.6).
Ungzip it, untar it, cd to the "Cheddar" directory, and start it:
./cheddar test.cheddarThere is also a Readme-file which, of course, nobody ever reads.
Thorsten Ratzka created a nice display of the uv-plane-coverage. I added a print-function to it, and a print button in the baseline-window, since nobody remembered that you can actually print the baseline-diagram...
The size of the diagram is now automatically adjusted to be large enough for all objects. If the diagram is larger than the window, then one has to scroll down to see the objects at the end of the list.
The e-mail- and www-addresses have been changed from Sterrewacht Leiden to LSW Heidelberg. Please note that I do not read e-mail sent to my address in Leiden any more, since about 104% of the messages are SPAM.
With tcl/tk version 8.5, the Postscript-output looked very funny. This has been fixed.
The window showing the projected baseline will no longer crash if a new object list loaded.
"macified menus": On Mac computers, the menu bar is at the top of the screen.
The baseline-handling is even more foolproof than before. I won't tell you what has changed, you would only try to outsmart (or outfool) it.
Fixed another bug in the code that reads the baseline from the input-file.
|Released Version 2.1. New bugs and features are:
|Disabled the undocumented feature that promoted the new baseline-window. Cheddar now reads the baseline from the input-file.|
The main window (before version 2.5):
