! ========================================================== ! ================= Dear VLBA operator, ================= ! ========================================================== ! ! We are sending you a revised keyin file for our next ! observations BH083 (bh083c.key) in this e-mail. ! ! Our proposal is approved for dynamic scheduling for ! 4 times 7.0 hrs centered at LST 5.5h (Pie Town). ! The first observation has already been carried out on ! 2001 September 24. ! We would like to carry out further 3-times monitoring ! observations with the interval of 2 months, using ! this keyin file (bh083c.key). ! ! In this file, we have revised the source positions for OMC-2. ! ! I would greatly appreciate for your kind considerations. ! ! Sincerely, ! Tomoya Hirota ! ! ========================================================== ! ! BH083C: VLBA obs. BH083 ! !
