GUEST OBSERVER PROPOSAL PREPARATION - TARGET TABLE

This document provides instructions for the creation of the Target Tables to be included with Guest Observer proposals. The target tables generally provide all the information required by the Kepler Science Center to incorporate GO sources within the observing list. Table fields are described below with an example. If a proposal includes targets within two campaign fields, then a separate target table should be prepared for each field.

Example K2 Proposed Target List
 
ATTRIBUTE
DESCRIPTION
Object
The Ecliptic Plane Input Catalog (EPIC) ID number. This attribute can be determined by using the Kepler Target Search page. The EPIC ID is coupled to celestial coordinates and magnitudes. If the proposed target does not have an EPIC ID number please use a unique identifier, common or catalog name for this source, and supply the J2000 celestial coordinates in the Right Ascension and Declination columns of your target table.
Right Ascension
Right Ascension (J2000) of the center of the desired aperture. Celestial coordinates are only required if the target is not listed in the EPIC Target Search page. Adhere to decimal degree format.
Declination
Declination (J2000) of the center of the desired aperture. Celestial coordinates are only required if the target is not listed in the EPIC Target Search page. Adhere to decimal degree format.
Kp
The apparent magnitude of the target in the Kepler bandpass. The combination of celestial coordinates and magnitude are the primary data required by the Kepler Science Center to calculate target pixel masks. The Kepler magnitude for most sources can be obtained from the EPIC Target Search page. If no Kepler bandpass magnitude is provided in the EPIC, it can be estimated. If the magnitude entered here is brighter than the EPIC magnitude, then the user-supplied magnitude will be adopted. For highly-variable stars, list the brightest predicted magnitude.
Cadence Mode
The observing mode requested. Long cadence (30-minute) mode or Short cadence (1-minute) mode.
δRA
Proper motion of the target in units of arcsec per year. This information is optional and should only be provided if the proposer disagrees with the proper motion provided in the EPIC.
δDec
Proper motion of the target in units of arcsec per year. This information is optional and should only be provided if the proposer disagrees with the proper motion provided in the EPIC.
Extent
The radius of the semi-major axis of an extended target such as a galaxy. To reiterate, this is the radius, NOT the diameter i.e. the furthest distance that structure extends from the target coordinates provided. This column should be ignored if all targets are point sources.
Comments
If a target is non-standard, provide a brief description of non-standard table entries including: (a) user-supplied magnitude; (b) user-supplied coordinates; (c) extended sources; (d) the amplitude of highly variable stars, (e) high proper motion stars; (f) custom mask requests. Comments should be expanded upon within the text of the science justification of the proposal.

Each campaign target table must appear in two places:

  1. Embedded within the body of your uploaded proposal package to NSPIRES
  2. As a separate electronic file submitted directly to the Kepler Guest Observer Office

Instructions on how to provide both versions of the table are given below.

K2 Target Table Submission
  1. Download the template file written in Microsoft Excel format: K2-Cnn-propnum-PINAME.xls
  2. Populate the table using either Microsoft Excel or the freeware OpenOffice package. Insert additional table rows if needed, one per proposed target
  3. Copy / paste or encapsulate the table into the submission package between the science justification / technical management section and the PI's biography
  4. Rename the Excel spreadsheet according the format K2-Ccampaign-no-propid-PIname.xls, where propid is the proposal ID number assigned to the proposal by NSPIRES at the time of submission and PIname is the surname of the PI. An example would be K2-C04-0097-SMITH.xls
  5. Attach the renamed spreadsheet to an email and send it to the before the proposal deadline
