vetrr

vet the redshifts for the CGM^2 galaxy catalogue (PI J. Werk)

Requirements

• python
• numpy
• scipy
• matplotlib
• astropy
• h5py
• future
• PyYAML
• linetools

How to run vetrr

Example:

vetrr_vet_rr J1059_1441_m08_rr.fits test_vetted_rr.json --coadd_file=J1059+1441-08_coadd.yaml

vetrr_vet_rr is a script that will start the gui. It takes 3 arguments:

• output from RedRock (fits file with rr in it)
• vetted redshifts json folder. Lets use the convention JXXXX+XXXX_vetrr_your initials.json
• coadd_file: JXXXXXXX-<mask_number>_coadd.yaml created by the redux software

Commands to use in the GUI:

vet red rock using the gui

vetrr_vet_rr J0914_2823_m01_rr.fits J0914_2823_m01_vetrr_MW.json --coadd_file=J0914+2823-01_coadd.yaml

use 'vetrr_auto' instead

• vetrr_auto
• or to create a new output with your initials
  • vetrr_auto -i=<your initials>
• or
  • vetrr_auto --initials=MW where MW are your initials

list of in GUI commands:

• & Toggle through ZQ
• '#' Toggle through RedRock Guesses
• % Set z=0 (for stars)
• 9 Skip to next spectrum with ZQ=-99
• x Next spectrum
• S = smooth
• Y = decrease
• W = unzoom
• pressing 'b' = bottom where cursor
• pressing "_" goes to Halpha
• pressing "*" goes to [OII] doublet
• pressing "(" goes to CaII absorption
• pressing ")" goes to [OIII] 5007 lines
• press "[" and "]" to pan left or right

Redshift quality of fit ZQ

• 4=awesome
• 3=single line but confident in the redshift
• 2= Not an option
• 1= I've identified a spectral feature but am not confident in the redshift
• 0 = ok spectrum but nothing to key on
• -1 = junk
• -99 = un-vetted
