2. Filename structure
<Camera>_<SCET>_ID<LEVEL><PID>_<ID>_F<FWM1><FWM2>.img
<Camera> - NAC or WAC
<SCET> - Acquisition time in UTC (YYYY-MM-DDTHH.MM.SS.SSSZ)
<LEVEL> - CODMAC processing level
<PID> - DPU Processing ID
<ID> - User defined image ID (10 digits)
FWM# - Filter Wheel position
Example:
WAC_ T Z_ID17_ _F12.img

3. Filename structure 2 CODMAC Levels:
Level 0: TMI formatted uncalibrated data
(header un-calibrated – Non PDS - Decoded)
Level 1: Raw PDS images
(header calibrated – Image data in raw DN)
Level 2: Radiometric calibrated PDS images
(header calibrated – Image data in Wm-2sr-1nm-1)
Level 3: Geometric calibrated PDS images
(header calibrated – Image data in Wm-2sr-1nm-1 – Geometry Corrected)

4. Filename structure 3 PID: - Instance ID of image
The DPU can transmit the same image in multiple formats
0: Raw 1: Raw 2x2 bin 2: Raw 4x4 bin 3: Raw 8x8 bin
7: Wavelet Compressed Image 8: Thumbnail image
9: Software rebinned image
ID: - User defined image ID
Numbering Convention:
FFFUUUUIII
FFF = FCP ID Number
UUUU = User specified ID number
III = Image index within FCP

5. EDR format PDS Images PDS formated labels with embedded image data
Header human readable (in text editor)
PDS compliant labels
Same format as we need to deliver to the PDS imaging node in the end.

6. PDS - IDL Library
An IDL library exists for handling the Osiris PDS files (Work in progress )
Syntax compatible with OsirSoft
Can extract the various binary objects from the PDS files
Delivers motion calibrated shutter pulse data
Can modify and save PDS files
OsirSoft function d_xxx() replaced by p_xxx() but with same syntax.
Will accept OsirSoft header macros for header access

8. Calibration Pipeline Structure
Level 0 -> Level 1
No image data conversion, but header data calibrated. Output in PDS format.
Level 1 -> Level 2
Image data radiometric calibrated, but still with 1:1 pixel correlation to the raw data
Level 2 -> Level 3
Image data geometrically calibrated. No longer 1:1 pixel correlation with raw data.
