JCMT RxA3 ACSIS Standard Spectra

The table below contains the average spectra of all good quality observations
obtained between April 2007 and December 2008 (the 2007 spectra are
in the list of
current cals).
Good quality means line temperatures which are internally consistent and also consistent with RxA3/DAS data (if existing), and with good baselines.
The spectra were added with ORACDR (using the narrowline
or broadline recipe (no line forest recipe is available yet)).
In the narrowline (broadline) recipe a second (first) order baseline is subtracted.
For the
moment only 250 and 1000 MHz bandwidth spectra are shown (resolution 30 and
488 kHz).
The numbers in brackets are the peak TA* of the strongest
line in the spectrum and number of observations existing for the
particular combination.
All spectra show identifications of lines in the band (signal sideband in
blue and image sideband in red.
The identified lines
are those which are listed in JCMTOT (and therefore in SPLAT).
In a few cases the baseline of the only available spectrum is not very good.
These spectra will be removed when more data become available.
