Data Set Overview
This data set contains products acquired by the JunoCam
This data set uses the Committee on Data Management
and Computation (CODMAC) data level numbering system.
The JunoCam EDRs are considered Level 2 or Edited Data
(equivalent to NASA Level 0). The EDRs are reconstructed
from Level 1 or Raw Data.
JunoCam products are produced by the junomakepds.py program from
the format internally used at the JunoCam Mission Operations
Facility (MOF). This program reads a JunoCam image file, extracts
information from its headers, formats and attaches the PDS labels,
and appends the image data.
All JunoCam images must be a multiple of 16 pixels in both width
and height. Images are broken up into subimages (also called
fragments), and each fragment is transmitted separately. Raw and
predictively compressed images are reconstructed by concatenating
all of their image fragments and then processing; transform
compressed images are processed a fragment at a time. A JunoCam
data product consists of one image with decompression applied.
For each image file, a header identifies various properties of
the image and contains a file offset to the data portion of the
image. The image data are then appended to the end of the file.

Record (RDR) PDS Data Products Software Interface Specification (SIS)
for further details on the JunoCam data products.
