Export Data Formats and Media

Spectral and VL Data Files, Image Files, and Flat Field and Dark Count Files will all be in FITS format. They will conform to FITS standards described in TBS with Binary Table Extensions as described by Cotton & Tody (Binary Table Extension to FITS: A Proposal, Sept 1991). Keywords in the FITS headers will conform to the suggestions of Howard & Thompson (Proposed Keywords for SOHO, Sept 1992). A list of Keywords for Spectral Data Files is given in Data Processing Requirements for the Ultraviolet Coronagraph Spectrometer. Keywords for Image Files and VLD files will be given in TBD.

Modest sets of data can be provided over Internet. A single exposure of a UV detector will be up to 1 MB, and a ``typical" Spectral Data File is likely to be a set of exposures at 10 radii, or 10 MB. Thus a few typical Spectral Data Files per day could be exported via Internet. A Spectral Data File containing a large number of exposures, or a data set containing many Spectral Data Files can be exported from the SAO or Italian Data Analysis Facilities on Exabyte tape or optical disk.
