Grids:
Any observation intended to be part of a grid must have other similar
pointings within 1 degree to qualify for a reduced slew tax. To be clear,
in the final grid, no pointing may be farther than 1 degree from its
nearest neighbor. Individual pointings within a grid may be entered as
separate targets. Alternately, for a large number of pointings
with identical observing parameters, you may specify all pointings by
entering the average R.A. and Dec of the grid pointings in the
R.A. and Dec fields above, and then also specifying the 3 general grid
parameters below. Proposers MUST prepare a detailed description of the
grid positions (preferably a figure) to the CXC director (or his designate)
upon request.

V-Magnitude of Target
CCDs On:
Y (Required), N (turn off) or Off# (Optional with Turn-off order)
For example, Off1 should be the first optional CCD, meaning that it should
be the
first optional CCD to be turned off.
Most science programs should specify a total of 4 or fewer required CCDs .
All science programs that request a total of 5 or 6 CCDs must
specify Optional CCDs.
If the science requires 5 or 6 CCDs, proposers should state this in the Remarks field.

| Additional spatial windows : If you need to specify more windows, define them in the space below, one per line, with the following comma-delimited values: window order (4-36), chip ID (I0-S5), sampling frequency (0-255), starting column and width, starting row and height, lower energy threshold (0.08-15.0 keV), and energy range (0.1-15.0 keV).

- You may want to use the
PRoVis
tool to investigate Chandra spacecraft
roll, pitch and visibility for your target as a function of date.
Window Constraints
Use the largest viable window.
Do not enter window constraints merely to indicate periods of sunblock,
as these are accounted for by Chandra Mission Planning.
The format for entering dates is dd-mon-yyyy hh:mm
Roll Constraints
A roll constraint translates directly into a constraint on the day and time when an observation may be carried out. It should only be specified for cases in which a specific attitude is required to meet scientific objectives.
Phase Constraints:
Do you have a preference regarding the
distribution of observing time within the specified phase range?
If yes, describe the preference in the
additional constraints or preferences remarks field
and indicate Preferred in the associated menu.
Monitor Observations:
A maximum of 20 monitor observations are allowed. Additional entries
will be displayed when the
Exposure Time for entry 5,10,
and/or 15 is entered and the user
Verifies the form.
Do you want more than one observation of this target?
Grouping Targets: If this target needs to be observed within a relative time range with other targets in this proposal, select 'Y' for
Group Observation? and enter
a unique
Group Identification to be used for all targets in the group.
Enter the maximum time interval that you wish all targets to be observed.
This is often used for rasters or grids to facilitate alignment of roll angles.
Note: This will be counted as a constraint. It is normally not necessary unless T>20ksec.
Uninterrupted or Contiguous Observation Required?
Note: Ground-based observations other than the NRAO are only available as a Preferred constraint.
TOO Details
Is this the trigger target for a TOO?
Note:If this is the trigger target for a TOO, please specify the CXC
response window, trigger criteria and any followups.
These fields should NOT be specified if this target is a TOO followup,
even if the followup specifies a different instrument configuration than the
trigger target.
Exact TOO trigger criteria (400 characters)
Followup Observations
If followup TOO observations are being proposed, please enter the
exposure time, minimum and maximum time interval between preceding observation, and target number for each followup
in the Followup Summary form below. We strongly recommend
you refer to the detailed
instructions.
TOO followup instructions (1500 characters)
TOO Coordinated Observations:
Indicate all of the coordinated observations (simultaneous or
contemporaneous) associated with this TOO in the appropriate
box for coordination with other observatories. This
includes observations already approved under other programs,
even if time is not requested as part of this proposal.
Coordinated observations included only in proposal text
will not be recognized or accepted. For non-Chandra
observations approved after your Chandra proposal has
been accepted, you may request coordination
if and when you trigger your TOO. Any such request for
additional coordination or observing constraints must be made
to the Director and approved by the Chandra Director's Office.
For a constraint approved in this way, the CXC will try to
accommodate on a best efforts basis.
