PDS_VERSION_ID = PDS3 RECORD_TYPE = "STREAM" OBJECT = TEXT PUBLICATION_DATE = 2012-12-31 NOTE = "Description of the contents of the DOCUMENT directory" END_OBJECT = TEXT END DOCUMENT Directory Contents The latest version and other formats (e.g. ASCII text) of all documents for the Deep Impact and EPOXI missions are available in the Deep Impact and EPOXI documentation dataset, DI-C-HRII/HRIV/MRI/ITS-6-DOC-SET-V4.0, available online at http://pds.nasa.gov. However, several of the most useful documents are duplicated here in PDF/A format for convenience. Please note these may be an older version. Each document has a separate label file that describes its content and structure. Label files have the same name as the main document file but with an extension of ".LBL". The following files are found in this directory: DOCINFO.TXT - The file you are now reading. DAY_OF_YEAR_CALENDAR.PDF DAY_OF_YEAR_CALENDAR.LBL - "Day of Year Calendar" document, for perpetual and leap years, and a label file. EPOCH_EARTH_GEOM_2008MAR.ASC EPOCH_EARTH_GEOM_2008MAR.LBL - "EPOXI/EPOCh - Geometry for 18-19 March 2008 Earth Equatorial Observation #1" document and a label file. This document was provided by the EPOCh team and contains raw and interpolated observational geometry values covering the March 2008 Earth observation. The team used these values for their analysis although corresponding parameters based on final reconstructed pointing information are available in the archived data products. EPOCH_EARTH_GEOM_2009MAR.ASC EPOCH_EARTH_GEOM_2009MAR.LBL - "EPOXI/EPOCh - Geometry for 27-28 March 2009 Earth North Polar Observation" document and a label file. This document was provided by the EPOCh team and contains raw and interpolated observational geometry values covering the March 2009 Earth observation. The team used these values for their analysis although corresponding parameters based on final reconstructed pointing information are available in the archived data products are based. EPOCH_EARTH_GEOM_2009OCT.ASC EPOCH_EARTH_GEOM_2009OCT.LBL - "EPOXI/EPOCh - Geometry for 04-05 October 2009 Earth South Polar Observation #2" document and a label file. This document was provided by the EPOCh team and contains raw and interpolated observational geometry values covering the October 2009 Earth observation. The team used these values for their analysis because corresponding parameters in the archived data products could not be computed by the data pipeline due to lack of pointing telemetry for this period. EPOCH_EARTH_OBS.PDF EPOCH_EARTH_OBS.LBL - "Description of the EPOCh Earth Observations" document and a label file. EPOCH_EARTH_SEQ_2008.PDF EPOCH_EARTH_SEQ_2008.LBL - "EPOXI/EPOCh Earth Observations 2008 - Pointing and HRII, HRIV, and MRI Sequences" document and a label file. This document provides the pointing and observing sequence for EPOCh Earth equatorial observations performed during March, May, and June 2008 by the IR spectrometer (HRII) and the two visible CCDs (HRIV and MRI). In particular, the pointing section of the document describes each of the HRII scans of the Earth (for example, if the scan was from north-to-south or from south-to-north, the rate of the scan, etc.). EPOCH_EARTH_SEQ_2009.PDF EPOCH_EARTH_SEQ_2009.LBL - "EPOXI/EPOCh Earth Observations 2009 - Pointing and HRII, HRIV, and MRI Sequences" document and a label file. This document provides the pointing and observing sequence for EPOCh Earth equatorial observations performed during March and October 2009 by the IR spectrometer (HRII) and the two visible CCDs (HRIV and MRI). In particular, the pointing section of the document describes each of the HRII scans of the Earth (for example, if the scan was from north-to-south or from south-to-north, the rate of the scan, etc.). EPOCH_OVERVIEW.PDF EPOCH_OVERVIEW.LBL - "EPOXI/EPOCh Observations of Transiting Extrasolar Planets (and Earth)" presentation and a label file. EPOXI_SIS.PDF EPOXI_SIS.LBL - "EPOXI Archive Volume and Data Product SIS" document and a label file. This document describes the PDS datasets and data products for the EPOXI archive. EPOXI_CAL_PIPELINE_SUMM.PDF EPOXI_CAL_PIPELINE_SUMM.LBL - "EPOXI Calibration Pipeline Summary" document and a label file that provides an overview of the EPOXI calibration pipeline used to generate the data products in this dataset. INSTRUMENTS_HAMPTON.PDF INSTRUMENTS_HAMPTON.LBL - "An Overview of the Instrument Suite for the Deep Impact Mission" draft document and a label file. PDSDD_EPOXI.FUL PDSDD_EPOXI.IDX PDSDD_EPOXI.LBL - EPOXI local data dictionary file and its required index file and a label file. These files were used to verify the contents of this PDS dataset. QUATERNION_DESC.ASC QUATERNION_DESC.LBL - "Quaternion Description" document and a label file that describe the formation rules and the specific rotation accomplished by application of the values of the QUATERNION keyword in a data label to a vector. MRI_3_4_EPOXI_EARTH.TAB MRI_3_4_EPOXI_EARTH.LBL - This table and its label were generated to aid scientific research. The table contains image parameters and time- and geometry-related values such as mid-obs Julian date, exposure time, mission activity type, and description or purpose for each observation in this dataset. The values were extracted from the RADREV data labels.
