Output data

When completed there should be the following directories inside the DATA_DIR given.

calib              // contains input calibration files required by lbl 

                        (i.e. blaze and wave files depending on instrument
lblreftable        // LBL reference tables are added here

log                // Log files are stored here

models             // Any models downloaded are placed here

plots              // Any plots saved to disk are put here

science            // input spectra are put here (each in `{OBJECT_SCIENCE}` sub-directories)

lblrdb             // LBL RDB files are added here

lblrv              // LBL RV files (in `{OBJECT_SCIENCE}_{OBJECT_TEMPLATE}` sub-directories) 

                        are stored here

masks              // mask files for each object are placed here

other              // Other downloaded files are added here

templates          // templates are put here

Radial velocity outputs:

There are two main outputs a .fits file and a .rdb file.

The rdb file is compatible with dace (https://dace.unige.ch/radialVelocities/?) 

The fits file contains several extensions:

• Wave, DV, SDV, D2V, SD2V, D3V, SD3V images (each 2D with shape number of lines by the number of files)

• RDB0   is the reference table (fits bin table format)

• RDB is the fits bin table equivalent of the .rdb file

• PTABLE is the parameters used in this LBL run (fits bin table format)

Note the .rdb file and RDB extension in the fits file consist of the following columns:

• rjd     / reduced Julian date

• vrad   / the velocity (first derivative, dv) in m/s

• svrad   / the uncertainty on velocity

• d2v, sd2v, d3v, sd3v   are the second and third derivatives, and their respective uncertainties

• fwhm, sig_fwhm, dW and sdW   (FWHM and width (defined by CARMENES), related to d2v) and their respective uncertainties

• vrad_{key} and svrad_{key}    where 'key' relates to a specific measure of the radial velocity

  • • achromatic: 

    • chromatic_slope: 

    • photometric_band: 

    • photometric_band_{xlow-xhigh}   - dividing the detector into chunks

    • {Lambda}nm    - divided into chunks (where lambda is the center of the bin)

Notes:

_tc denotes a file has been cleaned of tellurics within LBL
