Sorry if this has been discussed anywhere but I can't seem to find much information about it - why is it that Voyager's pointing is so haphazard, as in this video of all the RAW Jupiter images - https://www.youtube.com/watch?v=bf5QJ8iFxUs?
I came across this link which says that pointing information for the images exists - http://pds-rings.seti.org/voyager/ck.html, but have also read on this forum that it's not very accurate. Would the information be useful in automatically aligning composite images and mosaics, or is it too coarse? Would it at least be useful in getting general alignments that could be refined by hand? And does anyone know why the cameras could not be pointed more accurately, or why accurate information could not be returned with the images? I assume it was some technical limitation, but just curious what it might be. |

i use gmic ( was called GREYCstoration ) but it evolved into including basically everything Imagemagic can do and the PDE based smoothing and inpainting
the pds imq ( yes the IMQ ) header has a x/y points for the reseau marks CODE Group = Reseaus Line = (12.6, 7.0, 4.0, -1.2, -4.6, -6.3, -8.0, -8.6, -8.9, -8.2, -10.0, -3.2, 22.9, 26.0, 22.0, 18.0, 17.0, 15.0, 14.0, 13.0, 13.0, 14.0, 8.0, 58.0, 55.1, 51.0, 48.0, 46.0, 44.0, 43.0, 42.0, 41.0, 41.0, 43.0, 44.0, 94.0, 90.0, 88.0, 85.0, 84.0, 82.0, 81.0, 81.0, 80.0, 81.0, 81.0, 131.9, 130.0, 118.7, 120.0, 169.9, 167.1, 164.8, 164.0, 161.8, 160.7, 159.9, 160.0, 158.5, 159.0, 159.0, 208.5, 208.0, 197.6, 197.6, 247.6, 245.5, 243.8, 242.6, 241.6, 240.6, 239.9, 239.2, 238.4, 237.7, 237.3, 286.8, 286.0, 277.2, 276.7, 326.4, 324.7, 323.3, 322.3, 321.5, 320.6, 320.0, 319.3, 318.5, 317.5, 316.9, 366.0, 365.2, 357.0, 356.5, 405.6, 404.2, 403.0, 402.1, 401.3, 400.6, 399.9, 399.1, 398.3, 397.4, 396.4, 445.2, 444.6, 436.4, 435.6, 485.0, 483.7, 482.8, 481.9, 481.1, 480.4, 479.6, 478.9, 478.0, 476.8, 475.5, 524.4, 524.2, 515.6, 514.6, 564.4, 563.3, 562.4, 561.6, 560.8, 560.0, 559.3, 558.4, 557.4, 556.0, 554.3, 603.5, 603.5, 593.0, 592.6, 643.1, 642.5, 641.0, 641.0, 640.2, 638.0, 637.0, 636.0, 635.0, 634.4, 630.0, 682.0, 682.0, 671.0, 669.3, 720.6, 720.9, 720.0, 719.0, 718.0, 717.0, 716.0, 714.0, 712.0, 710.0, 706.0, 757.7, 759.1, 758.0, 758.0, 757.0, 756.0, 755.0, 753.0, 752.0, 750.0, 746.0, 743.4, 795.4, 787.0, 787.0, 786.0, 785.0, 784.0, 783.0, 782.0, 780.0, 776.0, 778.0, 804.0, 810.7, 808.5, 808.5, 808.0, 807.4, 806.1, 805.0, 801.0, 798.0, 798.5, 787.0, 120.0) Sample = (0.4, 44.0, 119.0, 199.9, 278.0, 356.1, 433.9, 511.6, 588.5, 664.1, 737.1, 784.4, 6.0, 81.0, 158.0, 236.0, 314.0, 393.0, 471.0, 549.9, 626.3, 702.0, 772.0, -5.8, 43.0, 120.0, 199.0, 276.0, 355.0, 433.0, 512.0, 589.0, 666.0, 740.0, 792.0, 15.0, 81.0, 159.0, 238.0, 317.0, 395.0, 474.0, 551.0, 629.0, 705.0, 769.0, -4.6, 43.0, 744.1, 793.0, 15.3, 82.3, 159.0, 238.0, 318.1, 396.7, 475.2, 553.3, 631.0, 707.7, 773.5, -5.3, 43.0, 746.8, 795.7, 15.3, 82.4, 160.8, 239.0, 318.0, 397.4, 475.9, 554.3, 632.3, 709.6, 775.7, -5.1, 43.9, 748.7, 797.8, 15.6, 82.9, 161.3, 240.1, 319.0, 397.8, 476.4, 555.0, 633.2, 710.9, 777.5, -4.6, 44.4, 749.8, 799.3, 16.4, 83.4, 161.7, 240.4, 319.3, 398.1, 476.9, 555.5, 633.8, 711.7, 778.5, -3.8, 45.3, 750.4, 801.8, 17.5, 84.4, 162.3, 240.9, 319.7, 398.4, 477.2, 555.9, 634.3, 712.3, 779.2, -2.3, 46.4, 751.0, 799.8, 19.0, 85.4, 163.0, 241.4, 320.0, 398.9, 477.5, 556.4, 634.7, 712.7, 779.4, -0.5, 48.0, 752.0, 800.0, 21.3, 86.9, 163.9, 242.0, 320.6, 401.0, 479.0, 558.0, 636.0, 712.7, 778.0, 2.6, 50.4, 752.0, 799.5, 26.0, 89.2, 166.0, 243.0, 322.0, 401.0, 480.0, 559.0, 637.0, 714.0, 778.0, 4.5, 54.0, 129.0, 206.0, 284.0, 362.0, 441.0, 519.0, 598.0, 675.0, 751.0, 800.0, 22.2, 93.0, 168.0, 245.0, 323.0, 402.0, 481.0, 559.0, 637.0, 713.0, 785.0, 11.0, 56.6, 129.6, 205.8, 283.3, 361.5, 439.8, 518.3, 599.0, 675.6, 748.7, 794.0, 591.0) this was for the voyager "c1133337.imq" ingested into isis3 , before any work on it there is old c code for reading the imq's http://pds-imaging.jpl.nasa.gov/data/vg2-n..._0009/software/ http://pds-imaging.jpl.nasa.gov/data/vg2-n...re/softinfo.txt |
