| specClass; spec_cln | int16 | Spectral Classification
0=SPEC_UNKNOWN
1=SPEC_STAR
2=SPEC_GALAXY
3=SPEC_QSO
4=SPEC_HIZ_QSO high redshift qso > 2.3,
this triggers use of the Ly-alpha finding code
5=SPEC_SKY
6=STAR_LATE star dominated bt molecular bands M -> later
7=GAL_EM emmission line galaxy -- not set by the code
