[SURVEY-22] Split "FiberPosition" into "CobraPosition" & "FiducialFiberPosition"

Wed, 19 Feb 2020 04:31:37 +0000

I thought we could use "FiberPosition" table to manage the fiducial fibers as well, but the basic information for fiducial fibers is different from that for science fibers. So, I propose to add separate tables for "CobraPosition" and "FiducialFiberPosition". Information we should store is based on https://github.com/Subaru-PFS/pfs_utils/tree/master/data/fiberids

The current idea is that we prepare "FiberPosition" which includes:

"Fiber Position"

fiberId (Integer)
ftype (String) # fiber type e.g., cobra / fiducial
x (Float) # PFI x coordinate
y (Float) # PFI y coordinate

And then, we prepare "CobraPosition" and "FiducialFiberPosition" with "fiberId" as a foreign key

"CobraPosition"

cobraId (Integer)
fiberId (Integer)
fld (Integer)
cf (Integer)
mf (Integer)
cm (Integer)
mod (String)
x (Float)
y (Float)
r (Float)
sp (Integer)
fh (Integer)
sfib (Integer)
fiberIdLNA (String)

"FiducialFiberPosition"

ffId (Integer)
fiberId (Integer)
ff (Integer)
fff (Integer)
fftype (String)
fft (Integer)
x (Float)
y (Float)
