The Lichtenknecker Database of the BAV (LkDB) is a  large collection of times 
of minimum for eclipsing binaries of the northern  hemisphere. It is now 
available in the world wide web with a new  release (Rev. 4.0). It contains layout 
improvements and new  functions.
 
The user can choose the range of minima displayed in the  (O-C)-diagram
    *   display photoelectric and CCD observations only, supress  all others 
    *   supress uncertain observations 
    *   display minima within the time from ... to .... only (was  already 
part of Rev. 3.0)
The structure of data records has changed. We distinguish now between  
photoelectric and CCD observations and in this case optical filters are recordet  if 
reported by the observer. The user can display a table of data records  
correnponding with the chosen range of minima in a separate window.  There is a new 
function to download this table as a textfile for  further own data 
processing.   
Over that Rev. 4.0 contains an update of the database itself. Some new  
eclipsing binaries and many new minima published by IBVS and 〓Variable Star  
Bulletin“ of VSOLJ (Japan) have been entered. AAVSO and BAV came to  an agreement to 
integrate 〓Observed Minimum Times of Eclipsing Binaries“  published by the 
AAVSO in the future. The LkDB Rev. 4.0 now contains  1987 eclipsing binaries 
and more than 136,000 times of  minimum.

interested and send your proposals for further improvements or your critics  to
