Chandra Trigger TOO

** TOO Trigger Search Criteria

Only 1 field may be entered. Only TOOs that have not been observed will be retrieved. If the TOO has linked observations, only the first target may be triggered.

** TOO Trigger Observation List

Only TOOs that have not been observed will be retrieved. If the TOO has linked observations, only the first target may be triggered.

** TOO Trigger Observation

24 Hour Contact Information

Please specify any additional 24-hour contact information. The contact information should not be only the observer's daytime office number, but provide home phones, cell phones, and any additional information such as which contact information to use for what days/times.

Trigger Criteria

Although the Chandra Peer Review approved the scientific objectives and observing plan of the proposal, the TOO itself must also be justified. Please state why this particular TOO should be observed, i.e., why it is a good example of the phenomena addressed in the proposal. Required.

Response Window / Urgency

If necessary, please enter any changes to the approved response window. You must justify any changes that you request. Please note that faster response times may not be approved. please make sure that this includes all information required to actually plan and schedule the entire observation, as you may not have an opportunity for additional feedback or information before the observation occurs.

Target Name

Please specify the Target Name for this TOO. You may use the Resolve Name button to then fill in the coordinates from the NED or Simbad database.

Coordinates

Target coordinates may be specified in decimal degrees or in sexagesimal format (hours/minutes/seconds or degrees/minutes/seconds) using either colons or spaces as separators. If the user enters decimal values for RA and Dec, they are assumed to be in decimal degrees. To specify decimal hours, add "h" or "H" after the number. Examples:
RA Dec System Translation
20h 51m 06s+30d 41' 00" J2000 20 51 06.00 +30 41 00.00
20 51 06 +30 41 J2000 20 51 06.00 +30 41 00.00
20:51:06.0 +30:41:00.0 J2000 20 51 06.00 +30 41 00.00
23.7654 +0.6857 J2000 01 35 03.70 +00 41 08.52
23.7654h +0.6857 J2000 23 45 55.44 +00 41 08.52
18 12.5 -12 8.5 J2000 18 12 30.00 -12 08 30.00
For equatorial coordinates, if the RA is in sexagesimal format it is assumed to be in hours/minutes/seconds.

Observation Parameters

Please enter any changes to the previously approved observation parameters here. These changes will be sent to the Chandra Director's Office for approval. Not all changes may be approved.
