VizieR Online Data Catalog: YSOs detection with W filter (Allers+, 2020)

To search for brown dwarfs in star-forming regions, we have designed the W-band filter, a medium-bandpass filter centered at 1.45um. Our W-band filter can be combined with broad-band J and H photometry to create a reddening-insensitive index, Q.

We tested the efficacy of our filter by selecting candidate young brown dwarfs based only on their Q values. Using SpeX, we spectroscopically confirm 48/60 objects as having spectral types of M5 and later. If we include objects that met our selection criteria but were already spectroscopically confirmed prior to our SpeX observations, our confirmation rate is 95/107.
