We have derived the results presented here by analyzing the archival observational data obtained using Near Infrared Camera/Spectrograph (NICS) to retrieve sky brightness values. NICS has a 1K × 1K HAWAII-1 Teledyne detector with a plate scale of 0.5 arcsec/pixel. For the current study, we utilize the images observed using J, H, and Ks broadband filters of NICS. Further, we discuss the seasonal variation in NIR sky brightness at Gurushikhar over the last few years and its potential reasons. |
