This is the latest long-term schedule. Observations have been sorted into one-week intervals, taking into account solar, time, roll, and other constraints. It is our intent to follow this schedule. However, targets which are not constrained may well be moved forward or back in time to fill requirements of the short-term schedules. Targets of opportunity and any instrument or spacecraft anomalies may also cause observing times of targets to shift. This long-term schedule is our present estimate of future order of observations. Please be aware of the uncertainties.
Also notice that targets have been allotted to one-week intervals to fill only about half of real-time. This figure is significantly less than Chandra's available observing time. To achieve fully scheduled weeks, and to increase Chandra's efficiency we must allow the short-term scheduler some flexibility in target choice. This is done by reserving a pool of unconstrained targets with broad viewing windows, These targets are listed at the end of the long-term schedule, and may be scheduled at any time during the cycle to fill undersubscribed weeks.
The long-term schedule page has links to our database entries of the requested observing parameters as well as to images of the target fields of view. Observers are encouraged to review these entries and notify the Chandra Director's Office of any perceived problems. Observers may be contacted about a month prior to the detailed scheduling of their targets for final confirmation of the observing parameters. Note that the images accompanying the target pages assume a roll angle appropriate for the middle of the week to which the target has been assigned in the long-term schedule. This approximation, made for initial review purposes only, may not always respect accepted roll constraints. This will be corrected in the final scheduling process, which may also result in different guide stars than those shown in the optical image. Also, those targets allocated to the pool may be moved multiple times; the roll angles for their images are thus unlikely to correspond to the final orientation. Updates will be issued at the time of rescheduling.
If simultaneous observations with other instruments are a vital part of your program and if they were part of your peer-reviewed proposal, a time-constraint should be already applied to your target. Barring malfunctions, it will be honored. After a proposal has been reviewed and accepted, the addition of constraints, or changes in object, position or exposure time will not be honored. If you have added coordinated observations later or if only a secondary part of the science, we cannot perturb the normal scheduling to give you a definite time.
NOTE: In the text of the long-term schedule, pool targets are marked with a "P", Cool Catalog Targets (CCTs) are marked with "C", and roll and pitch angles given are for the start and end of each observation's assigned one-week interval.
