Files produced by ORAC-DR from ACSIS data:


Ungridded:
----------
em001.sdf      - Ends of the frequency axis have been trimmed off.

thr001.sdf     - Thresholded time-series data. (Clips blatant spike)

ts001.sdf      - Time-sorted time-series data.

tss001.sdf     - Time-series data with median signal removed. (Removes
                    average signal prsent under whole array and all
                    channels)

Gridded:
--------

cube001.sdf    - Cube. What this actually is depends on the recipe used
                    and which type of file it is. For all group files
                    (starting with ga), this is the unbaselined cube,
                    straight out of MAKECUBE. For individual observations
                    (starting with a) reduced  with _ADV recipes, it's a
                    baselined cube (because the input time-series data
                    was baselined before MAKECUBE). For individual
                    observations reduced with "summit" recipes, it's the
                    unbaselined cube.

var001.sdf     - Cube with variance array added.


blmask001.sdf  - Baseline mask cube. Regions of emission have been
                    masked out.

bl001.sdf      - Baselined cube.

mbl001.sdf     - Baseline regions masked out.

reduced001.sdf - "Final" cube.

integ.sdf      - Integrated intensity image. Essentially the baselined
                    cube collapsed along its frequency axis, but with
                    regions without emission masked out, along each
                    line-of-sight. (I.e. 0th moment)
rimg.sdf       - Representative image. Same as the integ.sdf.

iwc.sdf        - Intensity weighted velocity/frequency map. As integ.sdf
                    but deriving the intensity-weighted "average" velocity
                    along each line-of-sight. (I.e. 1st moment)

sp.sdf         - Spectrum plucked from position of peak intensity in the
                    integ file.
rsp.sdf        - Representative spectrum. Same as the sp.sdf.

cont.sdf       - Continuum image. Essentially a cube collapsed along its
                    entire frequency axis. I believe this is only created
                    for REDUCE_SCIENCE_CONTINUUM reductions.

linteg001.sdf  - Integrated intensity image formed around the "first" 
                 line. I haven't done any work on identifying individual
                 lines or clumps or whatnot, so I believe these
                 are effectively equivalent to the integ.sdf files.
