Freebie: Heatmap Gradient Presets for Photoshop

I do alot of data visualization these days and heatmaps are often a big part of that. I couldn't find any good presets, so I decided to create my own. Hope you like them.

Instructions:
1) Double click the grd file to load the gradients into your presets.
2) Select the brush tool, with the following settings: https://www.evernote.com/shard/s54/sh/ac318aad-12ba-46dc-8b94-d9cc94d16222/7a467380e02ad5b5/res/44bb2462-bb38-44d8-810f-9760789868ae/skitch.png
3) Make sure your layer style has this setting: https://www.evernote.com/shard/s54/sh/426c6f98-0e67-43e3-b505-0ddd277ccb61/dfda6cd3a7338aac/res/2a554528-d30c-42c5-a390-cca1396a0c8e/skitch.png
4) Start drawing!

Use the example PSD file to get started, if you can't figure it out.
