| Description |
|
Stellar typing for flux calibration using the equivalent widths of available absorption lines. This is one of the options of stellar typing. The result of this method is compared with that of spectral fitting in PIPE2D-651 and |

This remains as a possible option for stellar typing because (1) it does not require the spectral whitening (we define the psuedo continuum around each absorption feature to compute EQ), (2) it does not require precise LSF (we just integrate the pixels instead of fitting them), and (3) EWs can be precomputed and the typing will be fast. |
