JCMT HARP 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 RxB3/DAS data (if existing), and with good baselines.
In a few
cases the second criterion was dropped because all existing HARP observations
were obtained a wrong K-mirror positions (probably). Such data will be removed
once better data become available.
The spectra were added with ORACDR (using the narrowline or broadline advanced
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 were summed (resolution 30 and
488 kHz). The
number in brackets is the number of observations existing for the particular
combination. For C18O and 13CO 250 MHz observations were
added where these lines were observed in two subband mode (resolution 60 kHz).
These are distinguished by an s before the bracket.
All spectra show identifications of lines in the band. The identified lines
are those which are listed in JCMTOT (and therefore in SPLAT).
