Calibration can proceed as normal from this point.
19.5 Advanced slicing of CVF data (CAM04)
This section introduces the CIA user to advanced concepts in slicing CVF data.
19.5.1 Up and down CVF observation
Since the LW CVF is split into two segments, one complete LW CVF scan must be performed in
two observations. This means that a complete up and down LW CVF scan is comprised of four
observations. Consequently, spdtoscd will output four SSCDs from the CISP data product.

CIA> /nowrite
CIA> cleaned_sscds = sscd_clean( raw_sscd )
Out of 345 SCDs:
5 are rejected due to mode
2 are rejected due to csh flag
8 are rejected due to qla flag
In total 337 are accepted

These four SSCDs may be concatenated into one SSCD with sscd concatene. Below, the
last three SSCDs are concatenated to the first SSCD.
