Query: AstroSat-CZTI as a hard X-ray Pulsar Monitor   The Cadmium Zinc Telluride Imager (CZTI) is an imaging instrument onboard
AstroSat. This instrument operates as a nearly open all-sky detector above ~60
keV, making possible long integrations irrespective of the spacecraft pointing.
We present a technique based on the AstroSat-CZTI data to explore the hard
X-ray characteristics of the $\gamma$-ray pulsar population. We report highly
significant ($\sim 30\sigma$) detection of hard X-ray (60--380 keV) pulse
profile of the Crab pulsar using $\sim$5000 ks of CZTI observations within 5 to
70 degrees of Crab position in the sky, using a custom algorithm developed by
us. Using Crab as our test source, we estimate the off-axis sensitivity of the
instrument and establish AstroSat-CZTI as a prospective tool in investigating
hard X-ray characteristics of $\gamma$-ray pulsars as faint as 10 mCrab.
