KGMATCH Search Output Columns


This document defines the catalog entries describing the KGMATCH Data Archive.

Mark
Clicking on entries in this column will mark the entry for retrieval. To mark all entries, click one of the buttons labelled 'Mark All','Mark public', or 'Mark Proprietary'. (Unmarking all entries can be done the same way using the appropriate button.) For missions with proprietary data, the mark button element will have a yellow background and a '@' symbol to indicate data sets not yet public.

To Retrieve:
Click the button labelled 'Submit marked data for retrieval from STDADS'. This will send all the marked data set names to the data retrieval page. Follow the directions on the displayed pages.

To Coplot:
After selecting up to 15 observations to be plotted, click on the "Plot marked spectra" button to coplot the selected observations.

The spectra that you selected will be automatically scaled to the full range of wavelengths and nearly the full range of fluxes (i.e., y axis plot scale runs from 0 (or .25 * the minimum flux for spectra with negative fluxes) to the 10th highest flux). Each spectrum is automatically assigned a color, up to a maximum of 15.

For plotting Kepler light curves, y-axis scaling is slightly different. Plots scale simply from the minimum to the maximum flux. It is also recommended that only Kepler light curves from the same target be co-plotted due to the differences in flux values.

The spectra are labelled by their dataset names, with a summary of the datasets plotted given below the plot. After inspecting the plot, you may wish to change the selection of datasets which are displayed. Use your browser "Back" button to do this.

Plot range
Adjust the minimum and maximum wavelengths (in Angstroms) and minimum and maximum fluxes (in erg /cm2/sec/A) to select the spectral region of interest and to exclude noisy data. Note Kepler light curves are in units of time and uncalibrated fluxes.

Plot dimensions
Adjust the X size and Y size in pixels to create the size of plot desired. The maximum dimensions are 850 by 640 pixels.

Redraw plot
Use this button to replot the spectra when you have changed the plot range or plot dimensions.

KIC Dec (J2000)
Declination (J2000) in decimal degrees. All but roughly 36,000 photometric standards, are within the Kepler FOV.
range: 36.6 to 51.4 degrees

AngSep
Computed angular separation between KIC and GALEX catalog positions in arcseconds.
range: 0.001 to 5 arcsec for the complete search, 0 to 2.5 for the more accurate search.

FUV
Magnitude in far-UV GALEX filter of GALEX matched object.
