Observation Search Page

Search
The Chandra Observation Catalog will be searched, based on the constraints entered on this page. Constraints may be specified for any, all, or none of the fields. If no value is entered for a field, that field is ignored for the search. If values are specified for a field, only observations that satisfy all of the search constraints are returned. This also applies to the multiple selection lists. The default for most lists is nothing selected. This is the equivalent to a blank data entry field (i.e. it won't be used as a search constraint.) For the multiple selection lists, no values selected is equivalent to all values selected. For more information see Multiple Selection Lists

Resolve Name
The user may use the Resolve Name option to find the position of a target object for a position search. The RA and Dec fields will be filled with the position of the requested object. This option is not available for a Range Search or if you have selected a file to upload.
Reset
Restore all of the fields to the default values.

Custom Package Page


This page allows the user to create their own custom package of products, including supporting products.

Note that there are certain low-level (telemetry, L0) products that are not available through WebChaser, because they may contain a mix of public and proprietary data. These products can be made available through a special request, but users are warned that their usefulness is extremely limited since they are not supported in CIAO tools.

Add Products to Retrieval List
Add the selected products to the retrieval list and go to the Retrieval List page.


Retrieval List Page


Browse Products
Display a list of data products for the selected observations. All users are allowed to browse all data products, including proprietary ones.

Retrieve Products
 Retrieve the data products specified by the selection on this page. All users are allowed to retrieve all products for public observations and the public products for proprietary observations. Users who log into a privileged archive account (e.g., a PI or a proposal account) will, in addition, be able to retrieve data products that are proprietary. The retrieved data products will be written to a tar file and the user will be advised on how to retrieve the tar file. Note that when an unauthorized user asks for products from a proprietary observation, (s)he will receive all products from that observation that are public, but not receive a warning that not all products are included.

Logging in to a proprietary account further provides the user with retrieval access to the proprietary products to which that account is authorized.
