There is in that collection a series of shots of the color wheel, with
file names:

100L2M1.JPG

....
That is a series of three shots, from MER 1 (M1), left camera (L),
filters L2, L5 and L6 which is roughly red, green, blue.


Can anyone shed light on the naming system JPL uses for their raw image
filenames? This is what I have figured out on my own:

Eg: 2 P 126553081 ESF 0200 P 2100 L6 M1 .JPG

2 = MER-2 (Spirit aka MER-A)

P = Pancam

9-digit decimal number = seconds since Jan 1, 2000
so: '126553081' would be 4-Jan-04 17:36. (4 hours slow though ??)

ESF/EFF/EDS = ? -- I note EFF is the predominant type; files are larger

4-digit decimal number = ? ('0200' in this case)

P = ?

4-digit decimal number = ? ('2100' in this case)

L = Left 'eye'
6 = Filter number 6

M1 = ? (I don't think Mer-1, as that is Opportunity)

Thanks for any insight.

PS Thanks v. much Joe for filter information.
