The SOUP's own config is pointed to from the camera config above. It consists of two sections, calibration and sequence file, as seen in the excerpt below.
# calibration SOUP_CAL_LINE:28 SOUP_CAL_START:-250 SOUP_CAL_STEP:5 SOUP_CAL_END:250 SOUP_CAL_MODE:0 # sequence file SOUP_SEQUENCE:soup/6302simple.seq #Full Stokes #LC1_6302:2167.0[0.00],4572.0[0.00],4572.0[0.00],2264.0[8.00] #LC2_6302:2991.0[0.00],2049.0[4.50],1339.0[5.50],1137.0[8.50] #Stokes V only LC1_6302:2333.0[8.50],7271.7[0.00] LC2_6302:2539.7[0.00],2539.7[0.00]
The calibration section is read while you are calibrating the SOUP (i.e. when in SOUP calib mode), while the sequence file section is only used when you are running an observation sequence (i.e. in Save all mode).
| SOUP_CAL_LINE: Spectral line reference number (see appendix D). |
| SOUP_CAL_START: Negative line offset from line center in mÅ. |
| SOUP_CAL_STEP: Line scan step in mÅ. |
| SOUP_CAL_END: Positive line offset from line center in mÅ. |
| SOUP_CAL_MODE: Band mode, 1 = wide band, 0 = narrow band. mode. |
| SOUP_SEQUENCE: Path to sequence file to use, see section 6.5 |
| # Full stokes: Uncomment following 2 lines to use 4 LC states |
| # Stokes V only: Uncomment following 2 lines to use 2 LC states |
If you are observing a line with an existing SOUP config file, all calibration settings and the path to the sequence file should be ok.
