Long tickmarks labeled with month name correspond to the 0:00 UT first day of this month. Longer tickmarks are 5-th 10-th, 15-th, etc. Days on the left scale run from bottom to top (declination is increasing with time), days on the right scale run from top to bottom (declination is decreasing with time). --~--~---------~--~----~------------~-------~--~----~ Navigation List archive: www.fer3.com/arc To post, email NavList@fer3.com To , email NavList-@fer3.com -~----------~----~----~----~------~----~------~--~---
