NICER observation list: Target ID 467501

Abstract

After a black hole transient has reached the bright and soft thermal-dominant state, it undergoes a months-long gradual decline in the same thermal state. These data contain minimal contribution from the nonthermal Compton and reflection components and as such are the gold-standard for spin measurements via X-ray continuum fitting. To account for source evolution and to ensure we accrue sufficient data in the critical thin-disk regime, we request 10x2ks observations, each spaced apart by 2-4 weeks to monitor a (roughly) Crab-bright transient in decline. We request up to two triggers over the next cycle, for a maximum of 40ks.
