+LSST (2023) Filters
+-------------------
+
+LSST filter responses are taken from tag 1.9 of the LSST simulations
+`throughputs package <https://github.com/lsst/throughputs>`__ and include a
+standard atmosphere with airmass 1.2 that is also tabulated in the same package.
+
+This tag follows the baselining of silver coatings on all three mirrors.
+
+The group name ``lsst2023`` is used to identify these response curves in ``speclite``.
+The plot below shows the output of the command below::
+
+    lsst = speclite.filters.load_filters('lsst2023-*')
+    speclite.filters.plot_filters(
+        lsst, wavelength_limits=(3000, 11000), legend_loc='upper left')
