Note: When accessing files, be aware of the different formats these files and tables are in (File Structures). If you pull the data out in the wrong format, your data might be
Using Netscape to download the data, position the cursor over the filename. Hold the "right" mouse button down, and a window will pop up. Move down in the window to "Save Link As...." and feel free to use all default values that come up, and placing the data in whatever directory is appropriate. For Mosaic, clicking on the link for a file will bring up a window indicating that it will be saving the file as binary. This is misleading and it does save the data as ASCII (assuming an extension of *.fit).

A cross-listing of the root names with filter and targetname is contained in the file aaa_readme.index. Both *.poly and *.fit files are in ascii file format. The *.poly files contain the polynomial fits (one file for x, one for y) for the reference transfer functions. The *.fit files contain the polynomial fits evaluated at 1 milli-arcsecond bins. The *.poly files require running through the FGS software before the plot can be printed but the *.fit files can be printed with any plotting software available.
