Back to: FrontPage Go to: BhBsPlan (Detailed Night Plan Step by Step) Starlist: starlist

Goal: We seek NaI (5891, 5897) and CaII (3937) absorption line detections in HIRES spectra of BHB stars. That is the primary goal of this program. We will also be taking observations of a very intriguing LLS for John O'Meara and Chris Howk for a potentially high-impact result (very low metallicity gas!). These observations will have to be taken in a different set-up. Their goal is to detect (or put strong limits on) MgII at z = 0.89759. Unfortunately, for the optimal BHB setup, the lines at ~5320 Angstroms will fall in our gap. So, they need a different setup.

Setup 3 hopefully puts 5891 coverage in 60th and 61st order, increasing S/N by sqrt(2). June 13 in Setup 3. March 29 in Setup 1. others in Setup 2.

rsyncing Data: go to 128.171.99.33:900 in a browser window. login as sshuser (ask for firewall password). Once logged in, choose standard. execute this command from a terminal window: rsync -avz hiresXX@hamoa.keck.hawaii.edu:/s/sdata125/hiresX/utdate ./

Observing Procedure/Exposure Times:

  1. Go to coordinates of the star and acquire. Guide on source.
  2. If you need a finder do the following:

Necessary Calibrations: We will need arcs, flats for both set-ups.

Conditions: This project can be done in poorer conditions. ALSO, it is pretty good for twilight!

Target List: Priorities go to close-in stars (low z value) with high radial velocities (hrv) and high galactic latitudes (glat). Priority 1 means highest priority, Priority 3 is lowest priority. Only 2 HST targets (listed at the top) need to be observed. The others already have Keck data.

Exposure Times: Computed with HIRES ETC to achieve S/N of 15 - 20 over NaI (5891/5897).
