NICER observation list: Target ID 366201

We have an already approved joint Chandra-HETG/NuSTAR program to study the Si edge region structure (a probe of both the ISM and the local dust environment of the source) in conjunction with the broad band continuum. Here we request the addition of NICER observations to improve our knowledge of the source's location along its Z-track, via both spectra and timing signatures, and to improve our soft X-ray coverage. Furthermore, we can use these joint observations to improve the knowledge of the NICER calibration in the 1-3 keV region, without interference from the known dust halo. Our Chandra observations will spatially resolve out contamination from the known dust halo.
