| Description |
|
To get a feel for how many spectrophotometric standards we have across the HSC footprint, we collect stars from the HSC database and apply magnitude + color cuts to select F-stars and estimate their spatial density. The density is of course dependent on the cuts we apply, but it would be useful to get a feel at this point and also to setup a machinery to estimate the stellar density for a given set of mag + color cuts.

Using the “crude” selection defined at PIPE2D-383 and the HSC objects with g < 23 at PIPE2D-382, F star candidates are selected and their density maps are created at each survey field. The figure is an example of the density maps. (A high density at R.A. ~ 31 deg is due to a star cluster. )

The methodology to estimate the spatial density of the selected F-stars was studied. We will re-make the density map using an updated selection criteria for F-stars. |
