I wrote up some documentation of the RV tables in the L2 files over the weekend (see this link), and I’m confused by a few things. The issues are:
The orderlets are inhomogenously named: orderlet1, orderlet2, orderlet3, CAL, SKY. Is there some reason for this? If not, I suggest that we use SCI1, SCI2, SCI3, CAL, SKY.
We’re missing uncertainties for orderlet1, orderlet2, and orderlet3. CAL and SKY have them. These are helpful for some applications, including one that I'm working on now.
The values for the keywords source1, source2, source3, source CAL, and source SKY are surprising to me. For example, source1 = GREEN_SCI_FLUX1. That much should be obvious from the name and will be true by definition. I thought that a source column might have values like “star” or a particular star name like “10700", and CAL might be the name of a calibration source.
For the times, we have CCFBJD, but we don’t have a human readable time. I suggest adding DATE-MID-PHW (photon-weighted midtime formatted like 2023-10-20T06:44:15.316).
Some keywords have spaces (e.g. 'source CAL'), which makes it hard to define variable names in code.
