------------
Stars with _jan2015 ending are recommended 1% spectrophotometric standards from 
CALSPEC.
They are remarkably precise standards and all standard star observations 
should produce identical flux calibrations.

l745-46a, hd26169, ltt4364, vma2, HD26169 have been standardized 
by Bessell and are not as good as the CALSPEC stars. 
HD26169 is a halo giant toward the Magellanic Clouds.

Most white dwarfs have high proper motions that move them appreciably each year.  

star 	   RA(2000) 	  Dec(2000)	pmra	pmdec
VMa2	  00 49 09.89 +05 23 19.00	 1.234	-2.713
L745-46A  07 40 20.79 -17 24 49.1	 1.577	-1.246
LTT4364	  11 45 42.92 -64 50 29.46	 2.64	-0.33

Finding charts from Aladin are attached. The red line indicates the direction the 
star is moving. If the red line does not start at the obvious star it is because
the image was taken earlier than the 2000 epoch position. 

L745-46A has a late-M dwarf companion to the W. 
EG131 has an late-M dwarf companion to the NW.

VMA2.png,  L745-46A.png, LTT4364.png, EG131.png are the charts.
vma2.ps, l745-46a.ps, ltt4364.ps, eg131.ps are plots of spectra.
