XMMMASTER - XMM-Newton Master Log & Public Archive

Overview

This is the XMM-Newton Master Catalog and Public Archive table which has been created from information supplied to the HEASARC by the XMM-Newton Project. It is periodically updated as necessary.

This database table contains the list of observations which have already been made by the XMM-Newton observatory, as well as those which are scheduled to be made in the near future (usually a a few weeks to a month ahead of the present). It does not contain observations which are scheduled to be performed further in the future, nor does it contain accepted observations which have not yet been scheduled. The list of all accepted XMM-Newton observations, including a number of ones which are unlikely to ever be carried out, such as accepted priority C targets, is available in the XMMAO Browse table.

This table includes entries for both pointed data and for data obtained during spacecraft slews. The slew observations all have obsid values beginning with the digit 9 and, because they were not made at a fixed position, lack any positional information such as RA and Declination.

Some XMM-Newton observations for which the archived data has become publicly available as indicated by the public_date parameter value, i.e., the proprietary period has expired, are not currently available at the HEASARC: such cases will have values of 'N' for the data_in_heasarc parameter. These datasets in most cases are available at the ESA XMM-Newton Science Archive (XSA) at http://nxsa.esac.esa.int/nxsa-web/.

For much more detailed information on the XMM-Newton instruments and their operation, please refer to the XMM-Newton Users Handbook at http://heasarc.gsfc.nasa.gov/docs/xmm/uhb/.

Parameters

ObsID
A unique XMM-Newton observation identifier made up of the proposal number, target number of the proposal, and exposure number of the target. This table includes entries for both pointed data and for data obtained during spacecraft slews. The slew observations all have obsid values beginning with the digit 9 and, because they were not made at a fixed position, lack any positional information such as RA and Declination.

PNo
The XMM-Newton proposal number to which the observation belongs. Note that the proposal number is the first six digits of the ObsID number.

Name
The name of the target of the XMM-Newton pointing.

RA
The nominal right ascension of the XMM-Newton pointing, in the requested equinox. Notice that the originating table contained the position in equinox J2000 with the right ascension given to a precision of 0.01 seconds of time.

Dec
The nominal declination of the XMM-Newton pointing, in the requested equinox. Notice that the originating table contained the position in equinox J2000 with the declination given to a precision of 0.1 arcseconds.

LII
The galactic longitude of the XMM-Newton pointing.

BII
The galactic latitude of the XMM-Newton pointing.

Time
The start time of the observation in UTC. Notice that the originating table gave the start time given to a precision of 0.01 seconds.

End_Time
The end time of the observation in UTC. Notice that the originating table gave the start time given to a precision of 0.01 seconds.

Duration
The actual observation on-time or duration as determined by the processing software, in seconds.

Scheduled_Duration
The planned duration for the observation, in seconds. This is the planned on-target time and includes the time required for instrument setup, which means that the actual 'science' time available will typically be lower than this.

Estimated_Exposure
The estimated duration for the observation in seconds. This is derived by checking for the time spent with the filter wheel (the MOS1 camera is taken as the reference) within the time window planned for the observation.

PI_Title
The title of the Principal Investigator, e.g., 'Dr.'

PI_FName
The first name of the Principal Investigator.

PI_LName
The family name of the Principal Investigator.

SAS_Version
The SAS software version which was used to generate the Pipeline Processing System (PPS) data products.

PPS_Flag
This is a flag which indicates whether or not the PPS data products have been generated at the XSA.

PPS_Version
Where available, this field contains the version of the Pipeline Processing System (PPS) that generated the PPS products and a date stamp designation when the PPS products was generated at the XSA.

ODF_Date
The creation date for the Observation Data Files (ODFs) from the raw telemetry data. If no date is listed, then this initial processing has not taken place.

Process_Date
The date of the last data processing.

Distribution_Date
The date when the final data products including the pipeline products and the ODFs were ready for distribution.

Public_Date
The date when the data products will become available to the public. This date is only approximate and subject to change.
