determination of the redshift range for each combination of excess IA band and emission line †

Table:

Figures:

these redshift ranges of z_min--z_max are calculated using λ_eff +/- FWHM/2 of each IA band and λ_rest of each line
- if z_max < 0, physically there is no chance detecting the emission line with the IA band: in this case, a straight line is inserted in the above table
- if z_max > 0 and z_min < 0, z_min = 0 is adopted in the above table
for single line emitters, z_ph is adopted to be the center of the possible redshift range: that is, z_ph = (z_max + z_min) / 2
- for the lines with z_min > 0, z_ph corresponds to the redshift corresponding to λ_eff
- for [OIII]+Hβ and Hα+[NII] lines, z_max and z_min are evaluated as the redshift at which either one of the lines is out and in the wavelengths of λ +/- FWHM/2 (22:43 9th July, 2015 from Y. Shioya)
for dual and multiple line emitters, z_ph is also adopted to be the center of the possible redshift range in which the combination of the IA-band excesses can be explained as a combination of the redshifted several emission lines
