If you have some data to submit, you can send them in a file to marie-lise.dubernet[at]obspm.fr. This file must respect these following syntaxes :


Article syntax

     @ARTICLE{
     author = {Buffa, G. and Tarrini, O. and Scappini, F. and Cecchi-Pestellini, C.},
     title = {H$_2$O-H$_2$O Collision Rate Coefficients},
     journal = {Ap. J. S.},
     year = {2000},
     month = {Februrary},
     volume = {128},
     issue = {2},
     pages = {597--601},
     url = {http://cdsads.u-strasbg.fr/cgi-bin/nph-bib_query?bibcode=2000ApJS..128..597B&db_key=AST},
     linkToData = {http://www.adresse1.com ; http://www.adresse2.com},
     adsnote = {Provided by the NASA Astrophysics Data System},
     keywords = {category1 : keyword ; category2 : keyword ; category3 : keyword}
     }
  • Highlighted syntax elements are the most important to respect,
  • Lines starting with a '@' or '#' are ignored. They can be used to put comments,
  • These entries must be present for all articles : author, title, journal, year. Others are optionals.

Collisional energy levels syntax

  • Title = give the Title of the data set (Author1 et al, Journal, Year).
  • Comment = give here a description of the data sets (please look at examples in BASECOL) and indicate reference to the data sets
Format of collisional energy tables
  • 1rst column = level label (from 1 to N)
  • 2nd column = energy (in cm-1)
  • 3rd and following columns = quantum numbers
  • For quantum numbers, could you please follow the description of quantum numbers indicated in the attached case by case document
  • Different cases have been defined, please contact marie-lise.dubernet[at]obspm.fr for these following cases:
    • Your data are described by linear combinaison of cases
    • Your data are described by other cases

Collisional rate coefficients syntax

  • Type of collisional rates = state-to-state, effective, thermalized
  • Title = give the Title of the data set (Author1 et al, Journal, Year).
  • Comment = give here a description of the data sets.
  • Ref = give the reference of the related paper or papers (full ref.) :
    • Reduced mass
    • PES = give some indication about the PES with ref
    • Method = indicate method used (example: CC, CS, IOS, QCT, etc..)
    • Range of energies = indicate range of energies
    • Xs
    • Basis set = indicate basis set
    • Precision = give precision indicated in your paper
Format of collisional rates tables
  • 1rst Line = the serie of N temperatures separated by one or several blank space
    For each following lines:
  • 1rst column i1 = initial level of molecule 1 (molecule 1 is usually the target)
  • 2nd column f1 = final level of molecule 1
  • 3rd column i2 = initial level of molecule 2 (molecule 2 is usually the collider)
  • 4th column f2 = final level of molecule 2
  • N columns containing the rate coefficients

  • Format of Temperatures = Integer (I4)
  • Format of levels = Integer (I4)
  • Format of rate coefficients = Double (Real*8)
  • If molecule 2 has no structure: i2=f2=1 (molecule - atom/electron) collision
  • If rates are effective rate coefficients for a given i2, then f2=i2
  • If rates are thermalized rate coefficients: i2=f2=1

: labelling of levels in COLLISION RATES TABLE, refer to the labelling of the corresponding table of energy of molecule 1 and molecule 2. Therefore even if your calculations do not include the use of the correct energies (IOS calculations, recoupling method for hyperfine levels), you must provide a table of energy (the quantum numbers will be correct, and the energies might be either approximate or taken from spectroscopic databases).

Fitting coefficients syntax

  • Title = give the Title of the data set (Author1 et al, Journal, Year)
  • Fit function = give the fit function, see example
  • Comment = give here a description if necessary
  • Ref = if any
Format of fitting coefficients table
  • 1rst Line = the serie of N coefficients
    For each following lines :
  • 1rst column = i1 = initial level of molecule 1 (mol1 is usually the target)
  • 2nd column = f1 = final level of molecule 1
  • 3rd column = i2 = initial level of molecule 2 (mol2 is usually the collider)
  • 4th column = f2 = final level of molecule 2
  • N columns containing the fitting coefficients
