Simulations using non-science images: the face of Einstein Simdata can be used to simulate any digitized image. In this example, we use the face of Albert Einstein.

Step 1: obtain your image. Typically from the internet.

Einstein.jpg

In this case, it is a jpg file.

Step 2: Convert your image to FITS

Various software programs have conversion to FITS enabled. The (GIMP) was used in this case. A handy list of FITS conversion programs is maintained by GSFC here

For the GIMP, start up the software

>gimp &

and in the main window select "Open" from the "File" menu.

The image will open up in a new window, you can use the GIMP to modify the image (adjust contrast, colormap etc).

Then, select "Save as" from the "File" menu in the window containing the image,
