Import FITS (Flexible Image Transport System) data.

Screen Shot and Video:

This app imports data from FITS files, including image, ASCII table and binary table.


Download the file Import FITS.opx, and then drag-and-drop onto the Origin workspace. An icon will appear in the Apps Gallery window.


  1. Click on the app icon to select one FITS file.
    It's recommended to save your project before this operation.
  2. Select the target HDU and load data or cards through context menu. They are always loaded to a new worksheet or a matrix sheet.
    • Load Data
      • ASCII Table
        ASCII table is loaded into a worksheet. Each field is stored as a column.
      • Binary Table
        Binary table is loaded into a worksheet. Each field is stored as a column.
        For fields repeat > 1 the data is stored as a matrix embedded in the first cell of the corresponding column.
      • Image
        Image is loaded into a matrix sheet. Currently only 1-D, 2-D and 3-D images are supported.
      • Random Groups
        Random groups are loaded into a worksheet.
        The first column indicates the group number.
        The last column is a link to load the corresponding data from the FITS file.
        The others are group parameters.
        Clicking on the data link, the corresponding data will be loaded as 1-D data, appended to the last column of the worksheet.
    • Load Cards
      Cards are loaded into a worksheet as one column of data.
  3. To open another FITS file, click on the ... button.
  4. Click on the Close button when done.

It would be nice to have support also for .tbl data import, which is often an alternative to .fits

Its primary use is image transport, with an extended and extensible header but also it can format tabular and multidimensional data. It is great to be able to import this format into Origin.
