==== Moscow 24-27 May 2011 ====

'''Part 1 - VALD3'''

'''Participants:'''

 * N. Piskunov (UU)
 * T. Ryabchikova (INASAN)
 * Yu. Pakhomov (INASAN)
 * U. Heiter (UU)

'''Topics discussed on 26 May 2011:'''

 * Status of VALD-3
   * Software: extraction software and EMS software is ready; new statistics handling has to be implemented in two places (parse_request and new statistics tool); synchronization is "outsourced" and is not anymore part of the VALD software
   * Data: Atomic line lists are complete for first three ionization stages; some data files for higher ionization stages have to be converted; Molecular line lists are available for TiO (two versions, with calculated or observed wavelengths)
   * Administration: Eric is VALD administrator; the main server is still in Vienna, Theresa is responsible to take action in case of any hardware problems.
 
 * Show Line as a web service
   Tanya suggested to provide Show Line as a web service with immediate reply rather than e-mail request.
   We agreed to implement this, since only a small amount of data is involved, and it is useful to see the result immediately.
   The option to send a Show Line request by e-mail will remain.
   This feature will be implemented by Yury with consultation of Eric.
 
 * Hyperfine structure constants
   Implement extraction of hyperfine structure constants:
   * generate separate data file for hyperfine structure constants (for a small set of test data to start with)
   * add flag in VALD record (last byte of comment field) indicating if data exist for the current line or add a line for the data file in the configuration file (similar to a replacement list)
   * implement option to extract hyperfine structure in preselect
 
 * The VALD mirror in Moscow was re-installed on a new server machine.

'''Part 2 - VAMDC/XSAMS'''
