Stellar Masses<br />
• Compare to MPA JHU mass catalog<br />
– Well tested stellar masses <strong>for</strong> <strong>SDSS</strong> galaxies<br />
– Uses Fiber photometry <strong>for</strong> fits<br />
• Assume Stellar Mass proportional to flux<br />
– Scale masses<br />
– Compare derived masses to scaled MPA-JHU<br />
