The beacon data is in FITS format; existing processing tools use FITS format and SSWIDL, so this is probably do-able. I'll contact the people on the STEREO team to find out more.
Is the Beacon data available via VSO? Is so, it would easy to search and process.

@dzarro Have you had a chance to work on this yet?
The basic code is in https://heliodocs.com/xdoc/xdoc_print.php?file=$SSW/gen/idl/atest/hv_beacon.pro . A couple of things come to mind for this.
hv_beacon.pro
to continually search for new data. This is not a big deal - there are other examples in JP2Gen.HVS_EUVI_A
and HVS_EUVI_B
helioviewer structure files. The beacon data should probably have their own structure files so that the filenames and the compression can be defined independently.There is also some discussion on how these data should be included in the data selector hierarchy in helioviewer.org. For example, we could have
STEREO-A > SECCHI > EUVI beacon > (wavelength)
or
STEREO-A > SECCHI beacon > EUVI > (wavelength)
This second one might be more sensible if COR1 and COR2 also have writeable beacon data.
A request we've had in the past is to make the EUVI wavelet-processed data available. This would be included as
STEREO-A > SECCHI > EUVI wavelet enhanced > (wavelength)
Since wavelet enhanced data has also been requested maybe it is best to distinguish different types of data from the source instrument at the detector level, i.e., EUVI beacon and EUVI wavelet enhanced.
It would be great if STEREO-A beacon images (particularly COR2) were available in helioviewer, as they are available with low latency (within minutes) compared to the full resolution images.
