Spectral Calibration of K$-$M Giants from medium resolution near-infrared HK-band spectra

Supriyo Ghosh, Soumen Mondal, Ramkrishna Das +1

We present here new medium resolution spectra ($\lambda /\Delta \lambda$ $\sim$ 1200) of K$-$M giants covering wavelength range 1.50$-$1.80 and 1.95$-$2.45 $\mu$m. The sample includes 72 K0$-$M8 giants…
