Package spectractor :: Module midworker

Module midworker

Spectractor submodule containing classes which interact with ESO MIDAS. Interaction with ESO MIDAS was made through pymidas module. With pyMidas we calculate heliocentric correction and with pyephem we calculate precession. Midworker class is the main part submodule.

Classes

HelVelCor
Calculate heliocentric RV correction for number of observation times.

MidWorker
Class with simple wrappers for some ESO MIDAS routines

Preparer
Class for image processing with MIDAS, against MIDAS sripting language =) We use MIDAS routines through pyMidas, but replace it with numpy and pyfits, if it is possible.
