Extracting spectrum of E9G10 of Xinglong 216cm

- cd pyexspec/bfoscE9G10/gui
- python app.py

• • if extract BFOSC the rot90 must be selected

• • bfosc orders reference

yfosc E9G10

Manually callibrate wavelength

• cd wvcalib
• $python wvclib_app.py
• • when set value of emission line, you shoud press "Enter/Return" keyboard after input the value into the table.
• • Finding the emission line automatically:
• • • BFOSC E9G10
• • • • npix_chunck = 8; CCF_Kernel Width = 1.5; num_sigma_clip = 3
• • • • Fitting Function: Poly2DFitter; Parameter : deg(X) = 4; deg(Y) = 6
• • • YFOSC E9G10
• • • • npix_chunck = 5; CCF_Kernel Width = 1.5; num_sigma_clip = 3
• • • • Fitting Function: Poly2DFitter; Parameter : deg(X) = 4; deg(Y) = 6
