UNPURCHASED PIXEL
Prior to a pixel being purchased only the basic location and price information is known, along with the merkle proof showing the unpurchased status.
{ x: , y: , msatoshi_price: }
PIXEL ASSET VALUE
The Pixel Asset Value embeds the binary data of the pixel color and coord information plus millisatoshi price.
Here's a breakdown of the data for the probed pixel. The hex values can be converted to decimal with a Binary Hex Converter tool.
Extracting the data reveals the following details which is rendered by the Sparkshot interface.
{ x: , y: , color: color, msatoshi_price: }
DATASET
The 2nd Preimage file contains all revealed Pixel Asset Values (The probed pixel is shown in bold), which is how we can show the currently paid for parts of the image.
The 2nd Preimage is SHA256 hashed to become the Preimage (shown below). Subsequently, that is SHA256 hashed to become the Payment Hash (also shown below). The Preimage and Payment Hash correspond to those values used to trigger the Lightning Network payment in exchange for the collection of Pixel Assets.
This can be independently verified by SHA256 hashing the data in a terminal bash session or via an online tool. Note that you must hash the byte values which the hex characters represent, not the ASCII string of hex characters.
$ echo "hex value" |xxd -r -p |sha256sum or use an Online Javascript Hash Calculator

MERKLE PROOF
The Merkle Proof shows the Pixel Asset Value as the leaf, combining up the tree to create the published Merkle Root of the art. This can also be verified by performing the SHA256 calculations independently.
