tablovas - Lovas spectral line catalogue manipulator (**preliminary**)
tablovas in=... [parameter=value]
tablovas manipulates
the Lovas spectral line catalogue in the frequency range between 0 and
about 3.4 THz (wavelengths longer then about 0.1 mm).
Selecting col=all has
been specifically designed to maintain the exact format of the database,
such that subselections can be made.
The following parameters
are recognized in any order if the keyword is also given:
- in=
- Input table,
in fixed 132-characters-per-line format. [No default].
- species=
- Species to check
for. The default is all. There are currently about 155 species in the catalogue.
Note names are case sensitive.
- col=
- Columns to print out. [Default: all].
** Note ** Currently selection by column names is not active. You can
either choose all, or something else, in which case a shorter version
with only name, freq will be output.
- freq=
- Frequency range to select. Two
numbers are required, with an optional third character string specifying
the frequency units given and requested (the catalogue’s numbers are listed
in Mhz, and this is the default). Note that if the units of freq are changed,
so will be units of err and lgint. We only support MHz, GHz and THz. See
example below.
- cutoff=
- Lower line intensity cutoff applied to the output.
Default: all will be printed. ** Note **: not implemented
- tab=
- Table
name, in which output is gathered. Default: terminal. Not implemented
The
format of the columns is as follows:
- 1. name
- molecular formulae
- 2. freq
- calculated
frequency, with 2 std.dev uncertainty. between brackets. (Units: MHz).
- 3. freqobs
- measured frequency, if available. (Units: MHz).
- 4. elow
- Lower energy level
(Units: cm-1)
- 5. rqn
- Rotational quantum numbers
- 6. ss
- symmetric state (E,
AA etc.)
- 7. hqn
- hyperfine quantum numbers F,F1
- 8. ri
- Relative intensity for
hfs, spin weights for CH3OCH3
- 9. sij
- line strength, Sij.($S_{ij}$) For several
species (u**2)Sij is also listed.
- 10. a
- Negative logarithm of the Einstein
coefficient, -log(A).
- 11. refs
- references (Roman Numerals)
The following
command lists all species present in the catalogue
% tablovas in=master.lis species=all col=name | awk ’{print $1}’ | sort
| uniq
or shorthand:
% tablovas master.lis all name | awk ’{print $1}’ | sort | uniq
tablovas is also suitable to be chained using Unix pipes and NEMO’s convention
to use ’-’ to designate a file on stdin/out (see getparam(3NEMO)
).
% cat master.list | tablovas - ... | tablovas - ... | more
