| Description |
|
FLUXSTD candidates were selected using the griz photometry only in the previous version of the FLUXSTD catalogs (v2 and earlier). But, the y-band should add a constraint as it straddles the Paschen break. Evaluate how the y-band improves the typing accuracy. |

Based on ~300 SEGUE objects, I confirmed that the effective temperature estimates improve when using all the grizy band data compared to the case of using only griz band data. We will use grizy data when available for the temperature estimates. |

By using the SEGUE data and treating the spectroscopic Teff as a reference, we confirmed the Teff estimates are improved when y-band data are added. We will go ahead and include y-band for the Teff estimates. |
