Calibration Data - Valid for 2011.12-2012.5

Scaling factors (Scaling to the results by S100+AC17) are shown here.
Please note that the errors are about 10 to 20 %, depending on baseline fitting range, the AC array used for the S100 observation (we recommend A17), velocity bin, and velocity range that is used for fitting.
We supply calibration data for some spectral lines; 12CO 1-0 (USB), 13CO 1-0 (LSB), C18O 1-0 (LSB), H13CO+ 1-0 (LSB), and CS 2-1 (USB) at the rest frequency of each line.

!!IMPORTANT NOTE!! (2013/08/09)
It should be noted that the intensity variability of AC45 compared to AOS has been reported recently (see "AC45 scaling factor"). Thus you may have an additional error of up to 40 % after you apply the BEARS scaling factors since we did not obtain the corresponding AC-AOS calibration data in 2011-2012 season.
