Using Odyssey data reduces the size of the previous error box by about a factor of eight: --------------------------------------------- RA(2000), deg Dec(2000), deg --------------------------------------------- Center: 7.405 (00h 29m 37s) -79.178 (-79d 10' 39") Corners: 8.180 (00h 32m 43s) -78.635 (-78d 38' 07") 7.610 (00h 30m 26s) -79.359 (-79d 21' 32") 6.536 (00h 26m 09s) -79.717 (-79d 43' 02") 7.206 (00h 28m 49s) -78.996 (-78d 59' 47") --------------------------------------------- The area of this box is 349 sq. arcmin, and its maximum dimension is 1.1 deg (the minimum one is 8 arcmin). A new map has been posted at http://www.ioffe.ru/LEA/GRBs/GRB130812_T39316/IPN/ Some improvement in this error box is possible.
