LWS Reduced Data
Raw LWS data are stored as a 6-dimensional FITS file which can be difficult to work with. We offer reduced images that convert the 6-D files into 2-D fits images by coadding the images at a given chop position and subtracting the images at the off-target chop position (all of this data is stored in the raw FITS file). See the description of our IDL code to create these files and the source code.
