How To Decode The MER Image Filenames

File name code

Below is a chart that will help you decode the 27 character file
names associated with the Mars Exploration Rover mission.
There is enough info below to allow you to make
stereograms and construct color pictures and determine
when and where the raw images were taken. Enjoy!

Character Function

1 Spacecraft ID
1 = Opportunity
2 = Spirit

2 Camera
F = Forward HAZCAM
R = Rear HAZCAM
N = NAVCAM
P = PANCAM
M = Microscopic Imager
E - EDLcam (Descent Imager)

3 to 11 Spacecraft clock
This is the number of seconds since January 1, 2000
at 11:58:55.816 UTC.

12 to 14 Product type
Product types are differentiated as having camera-induced
distortion removed (geometrically "linearized") or not
removed (nominal), and, as being thumbnail-sized or not.
Four special flag characters follow:

a) Beginning E - Type of EDR, which are raw with no camera
model linearization or radiometric correction. If no
beginning E, then it is a Reduced Data Record (RDR).
b) Ending T - EDR or RDR that is Thumbnail -sized.
c) Ending L - If no beginning E , denotes an RDR that is
Linearized, except for Thumbnail sized RDRs.
d) Ending N - If no beginning E , denotes an RDR that is
ThumbNail-sized and Linearized .

Valid values for MER camera instrument input data products:
Data Product Identifier

27 Product version number
Version identifier providing uniqueness for book keeping.

Valid values: 1, 2, 3, ... 9, A, B, ... Z

Example:

A photo with the file name
2P126471340EDN0000P2303L5M1.JPG would be from
Spirit (2), taken by the left PANCAM through the
535nm (green) filter. By matching the spacecraft times
(in this case 126471340) with other pictures that have a
similar time, you can find sets that were taken at the same time
of the day. Use similar sets to build stereograms and color
composites. This picture was downsampled (EDN) at
site 0 (00) and position 0 (00) (On the lander in this case!)
It was taken with command sequence P2303 for MIPL
(OPGS) at JPL and is version 1.

That compiles fine on Linux,

rawid ./
works OPK,
but
rawid 1M131649564EFF0544P2933M2M1.JPG
does nothing.
I looked at the code, in line 93 you do if(! isdr(filename) ) gotit is not etc...

The problem is in the routine isdr()
You do
if (fname[i] == '.')
fname[i] = '\0' ;

That basically already cuts of .JPG when you do a:
if (!isdr(fname))
{

/* here already it is 1M131649564EFF0544P2933M2M1 */
long patlen, gotit, gotone ;
char pat[MAXFN] ;

Beautiful site, I hear big ben?
Mars-birds?

That compiles fine on Linux,

rawid ./
works OPK,
but
rawid 1M131649564EFF0544P2933M2M1.JPG
does nothing.

Thanks Jan. I fixed the bug & updated the files:
