static get_species_ids(*args, **kwds)[source] [edit on github]¶

Get a dictionary of “species” IDs, where species refers to the molecule name, mass, and chemical composition

Parameters :

restr : str

String to compile into an re, if specified. Searches table for species whose names match

reflags : int

Flags to pass to :python:`re`

static query_lines(*args, **kwds) [edit on github]¶

Queries the service and returns a table object. Parameters ———- min_frequency : astropy.unit max_frequency : astropy.unit

Minimum and maximum frequency (or any spectral() equivalent)

chemical_name : str: Name of the chemical to search for. Treated as a regular expression. An empty set (‘’, (), [], {}) will match any species. Example: “H2CO” - 13 species have H2CO somewhere in their formula “Formaldehyde” - There are 8 isotopologues of Formaldehyde (e.g., H213CO) “formaldehyde” - Thioformaldehyde,Cyanoformaldehyde “formaldehyde”,flags=re.I - Formaldehyde,thioformaldehyde, and Cyanoformaldehyde ” H2CO ” - Just 1 species, H2CO. The spaces prevent including others.
chem_re_flags : int: See the :python:`re` module

energy_min : None or float energy_max : None or float

Energy range to include. See energy_type

energy_type : “el_cm1”,”eu_cm1”,”eu_k”,”el_k”: Type of energy to restrict. L/U for lower/upper state energy, cm/K for inverse cm, i.e. wavenumber, or K for Kelvin

intensity_type : None or ‘sij’,’cdms_jpl’,’aij’: The type of intensity on which to place a lower limit
transition : str: e.g. 1-0
version : ‘v1.0’ or ‘v2.0’: Data version
exclude : list: Types of lines to exclude. Default is: (‘potential’,’atmospheric’,’probable’) Can also exclude ‘known’
only_NRAO_recommended : bool: Show only NRAO recommended species?
line_lists : list: Options: Lovas, SLAIM, JPL, CDMS, ToyoMA, OSU, Recomb, Lisa, RFI
line_strengths : list: CDMS/JPL Intensity : ls1 Sij : ls3 Aij : ls4 Lovas/AST : ls5
energy_levels : list: E_lower (cm^-1) : el1 E_lower (K) : el2 E_upper (cm^-1) : el3 E_upper (K) : el4
export : bool: Set up arguments for the export server (as opposed to the HTML server)?
export_limit : int: Maximum number of lines in output file
noHFS : bool: No HFS Display
