Action Items Related to LAE Full Paper †

evaluating the EW(CIV) or EW(CIII]) significance of the following LAE candidates selected in Step 2 with N_ex^cons > 1
- the LAE candidates w/ N_ex^cons = 2:
  1. ID=1237451: (IA427, IA527) = (Lya, CIV) @ z_ph = 2.444
  2. ID= 994378: (IA464, IA709) = (Lya, CIII]) @ z_ph = 2.754
  3. ID= 996586: (IA464, IA738) = (Lya, CIII]) @ z_ph = 2.835
  4. ID=1110706: (IA464, IA574) = (Lya, CIV) @ z_ph = 2.764
  5. ID=1212266: (IA484, IA624) = (Lya, CIV) @ z_ph = 3.002
  6. ID=1260735: (IA484, IA624) = (Lya, CIV) @ z_ph = 3.002
  7. ID= 991118: (IA527, IA679) = (Lya, CIV) @ z_ph = 3.346
- the LAE candidates w/ N_ex^cons = 3:
  1. ID=1199858: (IA484, IA505, IA624) = (Lya, Lya, CIV) @ z_ph = 3.073
- this process is required to confirm whether they are also real emitters in CIV or CIII], while they are already confirmed to be real emitters in Lya

SED fits for low-z emitters
- necessary to evaluate the efficiency of our photo-z determination to LAEs (i.e., to see the number of low-z emitter candidates with z_spec consistent with high-z LAEs)

counting the number of LAEs separately according to the number of the detected bands among YJHK (N_{NIR,detect}) and excess IA band
- this information is required because the results of the SED fitting seem to be reliable only for the LAEs with N_{NIR,detect} >= 2
- the criteria of N_{NIR,detect} >= 2 can select the LAEs w/ log10(Mstar/Msun) > 9 and Δlog10(Mstar/Msun) < 0.5 dex (see email from Y. Shioya on 2015/06/10 20:27)

evaluating SFR(UV) instead of SFR(SED)
- to make the error-bar of SFR smaller
- L_λ @ λ = 1500 +/- 150 A and E(B-V) of the best-fit model SED --[Kennicutt98 relation]--> SFR(UV)

に関してですが、LAE 選出条件をこのように変更することに関しては同意します。
既に今日の打ち合わせで議論があったかもしれませんが、こうすると以前の N < 6 の条件では
保たれていた、他の low-z emitter の選択条件との consistency が保たれなくなります。
他の low-z emitter でもこの条件を採用することにした場合、サンプルが変わるかどうかを
見ておくのは重要かと思いますが、こちらに関してはどのようにお考えでしょうか。

LAE の非検出IA バンド数の条件は、LAE に対してSED fitting を行って得たbest-fit model が非検出IA バンドのデータの扱いのために観測データを適切に再現していないか否かを見て決めたもの。
low-z emitters に対して同じ条件を採用する必然はなく、low-z emitters についてもbest-fit model SED と観測データとの一致具合を見て決める
