INTEGRAL-REV3 Science Window Data Catalog

Overview

A Science Window (ScW) is a continuous time interval during which all data acquired by the INTEGRAL instruments result from a specific S/C attitude orientation state. Pointing (fixed orientation), Slew (changing orientation), and Engineering (undefined orientation) windows are all special cases of a Science Window. The key is that the same attitude information may be associated with all acquired data of a given Science Window. Note that it is possible to divide a time interval that qualifies as a Science Window under this definition into several smaller Science Windows using arbitrary criteria.

The INTEGRAL-REV3 Science Window Data Catalog (REV3_SCW) allows the search of Science Windows based on a set of keywords and the retrieval of the corresonding data products.

Parameters

scw_id
The name of any Science Window is the Science Window IDentifier (ScWID). This ID always consists of 12 digits of the form:

• RRRR is the revolution number of the S/C as defined from perigee passage,
• PPPP is the pointing number within the revolution and is always reset to "0000" when the revolution number increments,
• SSS is the subdivision number for a Science Window with a given RRRR and PPPP value. The minimum value of SSS allowed is "001" and always resets with a change of value of PPPP, and
• F is the type identifier of the Science Window with allowed values of (0) for "Pointing", (1) for "Slew", and (2) for "Engineering".

scw_type
