print(Splatalogue.query_lines.__doc__)
Queries the service and returns a table object.

The Splatalogue service returns lines with rest frequencies in the
range [min_frequency, max_frequency]

Parameters
----------
min_frequency : `astropy.unit`
max_frequency : `astropy.unit`
    Minimum and maximum frequency (or any spectral() equivalent)



Other Parameters
----------------
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 `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_lower_limit : None or float
    Lower limit on the intensity.  See intensity_type
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
displayHFS : bool
    Display HFS Intensity
show_unres_qn : bool
    Display Unresolved Quantum Numbers
show_upper_degeneracy : bool
    Display Upper State Degeneracy
show_molecule_tag : bool
    Display Molecule Tag
show_qn_code : bool
    Display Quantum Number Code
show_lovas_labref : bool
    Display Lab Ref
show_lovas_obsref : bool
    Display Obs Ref
show_orderedfreq_only : bool
    Display Ordered Frequency ONLY
show_nrao_recommended : bool
    Display NRAO Recommended Frequencies

Returns
-------
An `astropy.table.Table` object

In [17]:
