I just know everyone is going to want to try this for themselves
Steps and rationales in placing an S1 image under its buoy time frame:
rotate S1 of 05:46 22.11.19 cw 45º in ImageJ
measure scale between 85-86 at 2712.46 pixels or 813.7 pixels per 0.3 deg of lat
animation scale between 85.6 and 85.9 which is 0.3 deg of lat is 369.6 pixels
consequently the S1 needs to be downscaled by 45.42% to fit under animation frame 77 need to find 85.6 120 on the S1 to know how far to drag it.
given 85.0 and 86.0 corners, it will be 0.6 * 2712.46 = 739.2 pixels down from 85.0
add a blank layer and put a green dot there.
put a big red * over the Polarstern on the image
add frame 77 and final frame 100 overlays and co-slide to 85.6 120
autocrop to get rid of S1 that is not under frame 77.
note PS is 53 pxl left and 6 pxl down relative to buoy P204 on frame 77
for future PS put a magenta star 53 pxl left and 6 pxl down relative to buoy P204 on frame 100
sailwx is saying PS is at 85.7 120.3 on frame 100 which is at 04:30 on 11.23.19
put a orange star 27.4 pxls up from 85,7 (in a blank layer, don’t cover up data).
copy out P204’s route, color it cyan and translocate it from PS f77 to PS f100 for
that gives hypothetical intermediate drift that we can test with RAMMB
ship GPS is only 1 dp so has a large uncertainty orange box
save a new-from-visible png enlarged to ~700
repeat for all the frames that have a nearby S1 time and post to forum later
most of the steps are the same for all S1 and
steps vary simply if Uniq changes buoy animation scale and orientation
