| Abstract: |
The image display program AAOGlimpse has recently been extended to provide support for files using both HDF5 and NDF/HDS formats. Loosely defined formats present problems. Given an input file, what should be displayed? A FITS file may contain multiple images, and for the more flexible hierarchical formats things are even less clear: which of the many arrays in a structure actually represents the data of interest? Where is the wavelength or other WCS data? With HDF5 files, this becomes quite complex. This paper describes the way AAOGlimpse handles these questions, and emphasises the importance of agreeing conventions for how file formats are used. |
