Overview

OSO8 B&C Detector Lightcurves

Provenence

Parameters

Name
Nome of the Object

RA
The Right Ascension of the pointing.

Dec
The Declination of the pointing.

LII
The galactic longitude of the pointing.

BII
The galactic latitude of the pointing.

Lightcurve_No
The order number of the data set lightcurve.

Proposed_No
The order number assigned to the lightcurve a known bright x-ray source. A brighter source in the field of view at observation time may be the actual source for the lightcurve.

Actual_No
The order number assigned to the lightcurve of the brightest known x-ray source in the field of view at the time of observation based on past activity from the sources in the field.

Altname
The name that a particular x-ray source may be more commonly known as.

Detector
The letter identifier for the on board detector used for the observation.

Exposure
The 'exposure' parameter (given in seconds) corresponds to the effective exposure on source.

Count_Rate
The mean (or average) count rate determined for a particular lightcurve.

Count_Rate_Error
The error associated with the mean count rate.

Start_Date
File start time given as (DD/MM/YY HH:MM:SS).

Start_Time
File start time given as SHF (for browse) or MJD for W3browse

Stop_Date
File stop time given as (DD/MM/YY HH:MM:SS).

Stop_Time
File stop time given as SHF (for browse) or MJD for W3browse

Filename
The name given to the FITS file which contains some of the information used for this table.

Quality_Flag
A crude quality flag was assigned to each lightcurve to flag obvious problems. These flags are preliminary and do not account for all the potential problems. (10 = good, 5 and 4 acceptable).

Oriflux
Flux of the source.

Class
Browse classification, derived from the spectral type parameter, if one is available.
