SpecView is an analysis application and a 1-D spectral visualization that is Java Interactive. Created by Space Telescope Science Institute, it has the capability to read all Hubble Space Telescope instruments’ spectral formats delivered by M AST. It can read extracted HST ACS grism spectrograms as well. SpecView can also read data coming from different instruments in various file formats like FUSE, ISO, FORS and SDSS spectrograms, IUE, data from FITS and ASCII tables. It accepts data from Virtual Observatory and files in SPC Galactic Format. Allows reading and writing data on files IVOA SED Data model format. SpecView was originally created as a multi-purpose spectrum analysis and measurement tool. It was designed to make multiple 1-D spectral data sets that are stored in intricate file formats to become easier to visualize simultaneously. It also has the ability to save its state to files.
