What software is available to visualize and manipulate the data?
Most of the products are presented in the form of FITS binary tables. These can be read by many common astronomical reduction and visualization programs, including IDL’s astro library tools, IRAF, Fv, and VOplot. • How do I use the different products? The extracted spectra provided by KOA are browse products intended to give the user some idea of what the extracted spectra might look like when properly reduced. They are not meant to be a final, science-quality product that can be directly measured and analyzed to produce publishable science. It is recommended that archive users reduce the raw image data to produce their own science-quality spectra. However, the browse products may give some insight into data reduction issues that users should be aware of. For example, profiles will indicate whether the science object is point-like or extended, whether it is well-centered, and whether there are multiple objects in the slit. Traces can indicate how well the pipeline reduction followed th
