Setting up your MSBs:
Spectral Line Data Reduction:
- Spectral-Line Pipeline
Reduction Scripts (under construction!), the
reduction facility, and
how to configure orac_dr for ACSIS data(to be written!).
- DAS (retired):
data format: the DAS spectral line data format.
- SPECX (retired): DAS datareduction software, still used for
reduction of archived DAS data.
- CLASS: One can also use CLASS for the reduction of
DAS data, and for
ACSIS data (but some
header parameters are missing)
Older (before early 2006) DAS measurements and utilities that may still be useful:
Comparison Spectra and Telescope Efficiencies:
- Observations of a number
lines are used to verify system performance during
- Average spectra: These are the average of spectra
observed with the ACSIS backend under variable conditions, and judged to
be of acceptable quality. Until now there are
RxA3 spectra available.
- Main beam efficiencies have been derived from
all ACSIS observations made with RxA3, HARP, and RxW-D at 230.538, 345.796, and 691.473 GHz of the planets Mars,
Jupiter, and Uranus.
- Planetary flux data
can also be used for calibration.
- Standard Spectra:
These typically were taken with the DAS backend under controlled
conditions during a special campaign several years ago . Although
of good quality, systematic differences with newer receivers
warrant caution. All receivers used have been retired since: B3,
A2, B3i, and C2.
spectra: These were also taken a few years ago and aimed
to complement the standard spectra by adding data on
non-standard, but frequently used frequencies. They were selected
by hand as deemed 'representative', at a time that averaging large
numbers of spectra was not common practice. Some frequencies are
not very representative due to a lack of data. All receiver used
have been retired or upgraded since: A3, B3, WC and WD
- A web interface to our (DAS) standard spectra database is
available, as is an interface to the (DAS)
These databases contain all observations of standard sources and planets,
and derived aperture and beam efficiencies
