Gaussian Function / Normal Distribution / Bell Curve

After hopelessly poking around on the Net for a quality image containing a Gaussian, I decided to create my own.  These should have enough resolution for most purposes (2000 x 1000), and they're white on black for easy masking. The second one's shorter and fatter than the first, but please keep it to yourself so you don't hurt his feelings.

Feel free to copy them and use them for any purpose you'd like.
