masque: Mask used in the cross-correlation
masque indicates which mask was used in the numerical
cross-correlation.
A mask contains 'holes' corresponding to more than 3000
selected weak neutral metallic lines). Two such
masks are most used, R37000F0 and R37000K0,
for F0 and K0 spectral types, prepared for a
slightly broadened spectral resolving power of
37000. Other (private) masks are also used, in
particular one useful for A-type stars (prive4,
with fewer lines) and another for M-type stars
(prive1).
