<h3>K-corrections in 11 photometric bands</h3>
<p>As we compare photometric measurements for galaxies at different redshifts,
we have to correct them for the changes of effective rest-frame wavelengths
of filter bandpasses known as k-corrections. Their computation is an important step for obtaining the fully calibrated homogeneous dataset. We approximate k-corrections in 11 bands (from GALEX FUV to UKIDSS K) as 2D polynomial functions of a redshift and one of the colours.</p>

<p>This approach was proposed by us earlier (Chilingarian, Melchior and Zolotukhin, 2010) and coefficients of the polynomial approximations were provided in the <a href="http://kcor.sai.msu.ru/">K-corrections calculator service</a>. However, we did not compute the coefficients for GALEX FUV and NUV photometric bands. To compute them, as well as coefficients in the remaining 9 bands using a slightly updated approach described in Section 2.2 of our paper (Chilingarian &amp; Zolotukhin 2012). These coefficients are included in a <a href="http://kcor.sai.msu.ru/">new version of the K-corrections calculator</a>.</p>
