[K.Nagai]

Please forward this message to all  members of your organzation who might be
interested:
 
The BAV announces that Rev. 4.1 of the Lichtenknecker Database of  the BAV
(LkDB) is available in the World Wide Web from June 30,  2008 on. The new
version contains more times of minimum TOM) for  eclipsing binaries, some
improvements of the user interface, and some functional  enhancements.
 
Database Update:
 
    *   The LkDB now contains 1987  eclipsing variable stars with more than
137,000 times of minimum  (TOM).  
    *   The most important source for  new data is the _Information Bulletin 
on Variable  Stars (IBVS)_ (http://www.konkoly.hu/IBVS/issues.html) . Rev. 4.1 
of the LkDB contains all data of IBVS up to No.  5802 as far as they concern 
TOM for eclipsing binaries. It contains also the TOM published in  _Variable 
Star Bulletin  (VSB)_ (http://vsolj.cetus-net.org/bulletin.html)  by the 
japanese organization VSOLJ. Entering of TOM  published by AAVSO in _Observed  
Minima Timings of Eclipsing Binaries_ 
(http://www.aavso.org/observing/programs/eclipser/ebmono.shtml)  is still in
work and will be  finished with the next 
Version of the LkDB.
New functions and features: 
    *   To show an (O-C)-diagram and  data, the star name can now be chosen 
out of a list of constellations and out  of a list of stars belonging to the 
constellation. Entering the star name  directly is still possible.  
    *   The scaling of diagram axes was  improved.  
    *   The choice of the linear  elements from catalogues or the entering of 
own elements has been improved.  Default value are now the elements from the 
GCVS, if available.    
    *   The data belonging to a point in  the diagram can be shown in a 
separate information window when the cursor is  positioned on the point .  
    *   To check his own observations  the user has the possibility to enter 
his observed TOM and to generate an  (O-C)-diagram including this data.  
    *   The list of all observations  building the (O-C)-diagram contains 
hypertext-links to the source documents  IBVS and BAVM (BAV Mitteilungen) which 
are available in the world wide  web.

The BAV thanks their members Thorsten Lange and  Wolfgang Grimm. They both 
have done a lot of work and brought in  many good ideas to realize the user 
interface and the programs for the  (O-C)-Generator.
 
I hope for many users of the LkDB and for their feedback.
