VI-4 JPL Catalog Upgrades: New Tools, New Formats and New Interfaces BRIAN J. DROUIN, SHANSHAN YU, JOHN C. PEARSON, Jet Propulsion Laboratory, California Institute of Technology, Pasadena, CA
Cataloging Process New or Improved Spectra Published Search for related information, primarily dipole moment magnitude and direction Fit Spectra with SPFIT Predict Spectrum with SPCAT Predict Spectrum with SPCAT Document process, especially if different from literature Merge measured and predicted spectra Provide files on ftp and www server 6/18/2010
More Directory Files To assist with searching and database organization, e.g. searchable listing of entries that are known in ISM Catalog Structure Catalog file c*.cat Frequency of the line Estimated or experimental error ( indicates error is larger) Base 10 logarithm of the integrated intensity in units of nm2 MHz molecules degrees of freedom in the rotational partition function (0 for atoms, 2 for linear molecules, and 3 for nonlinear) Lower state energy in wavenumbers Upper state degeneracy negative indicates reported experimental error. Identifies the format of the quantum numbers given in the field QN. Quantum numbers for transition Documentation file d*.cat Partition function, dipole moment, prediction cutoffs, references Tags for references in c*.lin Archive files c*.int, c*.par, c*.lin dipole moment, prediction cutoffs, molecular parameters & Hamiltonian, experimental data Directory files catdir.html - links catdir.cat – entry name, # lines, log partition, update # Alternative Catalog Files p*.cat Same format but not merged with experimental data kept in subdirectory /catalog/prediction/ Energy files c*.egy Q uantum numbers for state Energy in wavenumbers Extended calculation of high J and tabulation of energies will enable dynamic Q(T) calculation Kept in archive Calibrated data files c*.dat simple format of experimental data, frequency & intensity – for species with poor or incomplete analyses 6/18/2010

Developing Standards IVOA - International Virtual Observatory Alliance International Virtual Observatory Alliance – ‘owners’ of SLAP – Simple Line Access Protocol SSLDM – Simple Spectral Line Data Model – The main use of the SSLDM is to provide data model support to the Simple Line Access Protocol, so to allow the consumption of Spectral Line List databases using a common/standard interface.
