Something I don't get: 083 worked before, but the first x5 picture in the set (assumed to be with 083) is black. Actually, all the 8.6MB pictures in groups #0, #4, #8 and #12 are black. Furthermore, pictures in the group #13 and #14 are not dual iso, and some of the pictures from the set have different ISO ratios.
#0 (13130002) => black
#1 (13130006) => 3.0EV, noise levels 5.99 14.93 14.86 5.82
#2 (13130010) => 3.0EV, noise levels 6.08 14.70 15.23 5.78
#3 (13130014) => 3.0EV, noise levels 6.21 14.74 15.15 5.83
#4 (13130018) => black
#5 (13130022) => 2.0EV, noise levels 7.10 14.95 15.26 6.94 => lower ISO increased from previous set
#6 (13130026) => 2.0EV, noise levels 7.07 14.96 14.95 6.96
#7 (13130031) => 2.0EV, noise levels 7.04 14.88 14.95 6.94
#8 (13130035) => black
#9 (13130039) => 0.99EV, noise levels 9.53 14.45 15.12 9.49 => lower ISO increased even more
#10 (13130043) => 1.0EV, noise levels 9.70 14.51 14.97 9.55
#11 (13130047) => 1.0EV, noise levels 9.67 14.76 15.31 9.49
#12 (13130051) => black
#13 (13130055) => 0.0EV, noise levels 9.82 14.77 15.20 9.57 (octave; image looks normal, cr2hdr refuses it)
#14 (13130059) => 0.0EV, noise levels 14.95 14.6 15.22 15.10 (octave; image looks like before, maybe with more hot pixels)
#15 (missing) => 0.0EV (predicted)
Previous sample:
13130002 => predicted 100/1600, got 4EV OK, noise levels 5.62 14.89 15.23 5.43
Image must be black if the two least significant bits are 0, unaffected otherwise.
Were the values in this sequence 0x083, 0x183 ... 0xE83, and was 0xF83 the missing one? If so, I'm unable to explain the results.
Were they 0x080, 0x081 ... 0x08E, and was 0x08F the missing one? If so, I can only explain the black frames and some of the ISO variations.
0x80 = 0b10000000 (predicted: black OK)
0x81/2/3 = 0b10000001/10/11 (predicted: 100/1600; got 3EV, expected 4)
0x84 = 0b10000100 (predicted: black OK)
0x85/6/7 = 0b10000101/10/11 (predicted: 200/1600; got 2EV, expected 3)
0x88 = 0b10001000 (predicted: black OK)
0x89/A/B = 0b10001001/10/11 (predicted: 400/1600; got 1EV, expected 2)
0x8C = 0b10001100 (predicted: black OK)
0x8D/E/F? = 0b10001101/10/11 (predicted: 400/1600; got 0EV, expected 1)
Assuming 0x60-0x6F to match the last two images, the predictions would be: 100/800 (3EV), 200/800 (2EV), 400/800 (1EV) and 800/800 (0EV). That seems to match, but why would you have chosen these values?
=> detective work failed; no idea what values you have set for this sequence. The sequence I've expected is 0x083, 0x183 ... 0xF83.
The FRSP images follow the same pattern (no surprises here).
