KEPLER Search Output Columns


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

Mark
Clicking on this box will mark the entry for retrieval.

To Retrieve:
The selected datasets will be downloaded in a single file. You may select the file type: .tar, .tar.gz, .tar.Z, and .zip. After selecting the file type, click on the "Download selected files" button and the selected files will be downloaded to your disk.

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. 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 Ångstroms) and minimum and maximum fluxes (in erg /cm2/sec/Å) to select the spectral region of interest and to exclude noisy data.

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

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

Kepmag Source
Source of Kepler-band magnitude
SCP, 2MASS, UNCAL, PHOTO, and TYBV. SCP - SCP values for sdssg and sdssr were used to compute KEPMAG using equation below . The error for KEPMAG is roughly 0.03 mag., NOCAL - No calibration to optical mag. possible, used for entries from non-optical catalogs. KEPMAG field is null. , 2MASS - Objects found only in 2MASS Catalog with no optical counterpart, KEPMAG is null, UNCAL - KEPMAG copied from a single color of the parent catalog, uncertainty could be 1.0 mag or higher, PHOTO - parent catalog contained a red and blue mag. obtained from Photographic photometry. Values used to compute KEPMAG on the basis of: sdssg=blue sdssr=red color=sdssg-sdssr if (color<=0.8) kepmag = 0.8*sdssr + 0.2*sdssg else kepmag = 0.9*sdssr+0.1*sdssg, internal photographic errors have errors of 0.2 mag suggest KEPMAG errors of 0.03 mag, TYBV - parent catalog is Tycho-2 and this gives B and V magnitudes. KEPMAG value computed from sdssg=0.54*b+0.46*v-0.07 sdssr=-0.44*b+1.44*v+0.12 using same transformation as above to calc. KEPMAG. Errors same as for TYCHO-2 catalog.
