Pair together light curve and radial velocity data of specified star I would like to create a web application that works with light curves and radial velocities of stars with exoplanets. I found a NASA bulk data download with both light curves and radial velocities (it's exactly what I'm looking for). However, I don't know how to pair together the light curve and radial velocity of a single star (without downloading the whole dataset).

For example, using the script below I can download the light curve of KIC 10666592, where there is 1 exoplanet:

wget -O 'kplr010666592-2009131110544_slc.fits' 'http://exoplanetarchive.ipac.caltech.edu:80/data/ETSS//Kepler/005/755/19/kplr010666592-2009131110544_slc.fits' -a search_33681064.log


Now, how can I download radial velocity data for this specific star? Scripts for radial velocity look like (there is no KIC in URL):

wget -O UID_0000522_RVC_001.tbl http://exoplanetarchive.ipac.caltech.edu:80/data/ExoData/0000/0000522/data/UID_0000522_RVC_001.tbl -a RADIAL.log


Is there any way to connect KIC (Kepler input catalog) and radial velocity UID?
An excellent page to get most or all names for a star is Simbad which also happens to know the Kepler IDs (KID).

Ont the other hand, every of the RV data files contains info on the star's identifier it belongs to in the header, e.g:


  \STAR_ID='HD 4628'


So using Simbad you should be able to do a cross-matching. SimBad allows scripted query and includes all alias names for stars; thus query for one known star name and look for identifiers found in the list of RV-observed stars or vice versa. Simbad allows to be queried via scripts, so you can make a short programme to do this task for you.

However I'm not 100% convinced that you necessarily find many matches between those two data sets; it's easier to do photometry than spectroscopy.
