FORS2 LSS spectroscopy of a sample of two Luminous Blue Compact 
Galaxies (LBCGs) and six spectral template stars for spectral 
cross-correlation.  Major difficulty will be that the spectral 
templates (OB name HD*) are so bright that they will saturate 
even with exposure times of 0.25 seconds.  P.I. suggests to 
observe the six spectral templates (HD stars) under poor 
seeing conditions and/or at high airmass (more specifically he 
claims that they will not saturate if "the product of the
seeing expressed in arcsec and the airmass is above 1.5").  
So please make sure to observe these spectral templates 
under much worse conditions than the actual science observation. 
Two science targets (ESO 400-43 and Haro 11), each consisting 
of four (nearly identical) science OBs.  Note that for Haro 11 
there are two orientations of the slit, each with two 
corresponding finding charts.  The P.I. is further requesting 
that these two target be centered on the upper (master) CCD of 
the FORS2 CCD mosaic in the initial acquisition. Also note that 
the composition of the OBs is somewhat unusual: After an 
acquisition with FORS2_lss_obs_slit_fast on a reference star, 
a through-slit image (just for reference) is taken with a 
FORS2_lss_obs_off_fast template (with no Grism specified), 
followed by the actual spectroscopic template.  Unusual, but 
should work.
