5. Example 2 - XD with Short-Blue + 111 l/mm grating - Point Source

In this example, we will reduce the GNIRS crossed-dispersed observation of the eruption of V3890 Sgr, a recurrent nova.

This observation uses the 111 l/mm grating, the short-blue camera and the 0.3 arcsec slit. The dither pattern is the standard ABBA, one set for each of the three central wavelength settings.

It is not uncommon to observe multiple central wavelength settings when using the 111 l/mm grating. The idea is to increase the wavelength coverage and to stitch the spectra together in the final step.

The data was originally published in Evans et al, 2022, MNRAS, 517, 4.

There is no API version of this example at this time.
