This is a 360 degree assembly from Sol454 PanCam half-size images (hey, guys, this is the widest images I ever made: >11kpixel! ); horizon tilt was deliberately left in order to measure it.

Scale is 0.55 mrad or 0.0315 deg/pixel and, based on the assumption that center of Voyager crater is approximately in the Noth direction, I obtained some interesting orientation data:
when opportrunity stalled, it was going approximatively in the south direction (azimut=180°).
Azimut of Viking crater (center)... 8.9°
Azimut of most depressed horizon... 138.8°
Herebus visible margin............. 181°-193°
Opportunity tilt................... 3.65°
"bad" dune orientation............. 34.5°-214.5°(obtained using also navCam images)

Azimut of most depressed horizon is compatible with a positive rover pith angle (center of rover body didn't reach exact dune crest).

wow !
this is one of the most impressive views of the wavy Meridiani Sea of Sand
we have seen yet


( hope, it will not be the final one for Oppy though

may Oppy's last pan be a 360 of the dunes at the bottom of Victoria ! )

I hope too!

Nice work! Impressive width and I think the quality of such downsamples is satisfactory for a pan. May you try an attempt with PTGui or do you abandon (with) it

Hi Tman, I didn't abandoned PTgui (I still have some problems in order to optimize it). However, for PanCam images, I found isn't very necessary, because distorsion is so small that manual stitching is good too and faster!...
I think I will make a flat-horizon version,... hey you and Nirgal could try to colorize it!

That one dune to the left is intense. It seems much bigger than the rest.
