integer |
| st_subt |
tt |
Encoded spectral subtype specified as an integer. See the Spectral Classification Tables. |
Range: 0 for unknown, 10 to 20 for normal stars, 10-12 for novae, and 10-16 for supernovae (see table ?) |
integer |

First encoded global peculiarity. Also indicates composites stars (p1=1). See the Spectral Classification Tables. |
Range: 0 to 9, 0 = unknown |
integer |
| st_p2 |

Second encoded global peculiarity (must have a different value from P1). See the Spectral Classification Tables. |
Range: 0 to 9, 0 = unknown |
integer |
| st_p3 |
P3 |
third encoded peculiarity, specific to a particular type or group of spectral types. Note for composites, P3 and P4 specify the TT value of the secondary star (e.g., for an A secondary (TT=12), P3=1 and P4 = 2). See the Spectral Classification Tables. |
Range: 0 to 9, 0 = unknown |
integer |

Detail Flag |
Flags special cases needing further explanation. |
d=0 normal, d=1 a classification in which a decimal subtype was truncated to an integer value, d=2 a ambiguous classification such as kA3, d=3 an unparsed classification |
integer |
| st_sflag |
Catalog Selection Flag |
Flags the cross correlation criteria used. Values from 9 to 19 refer to Skiff catalog correlations, 20-29 are for Sky_2000 and 30 indicates a Simbad entry was used. |
0 = no spectral type assigned, 9 = Skiff table correlation using another tors entry with same object_id 10 = Skiff table correlation using project-assigned name/aliases, < 5 arcsec separation, and latest publication date 11 = same as 10 excpet using Simbad aliases for name matching 12 = Skiff table correlation using Simbad target name/aliases, < 5 arcsec separation, and latest publication date 13 = Skiff table correlation using another tors entry with same object_id 14 = Skiff table correlation using < 5 arcsec separation, and latest publication date 16 = Skiff table correlation using target name/aliases, and latest publication date 17 = Skiff table correlation using another tors entry with same object_id 20 = Sky2000 table correlation using < 5 arcsec separation and HD target name 24 = Sky2000 table correlation using < 5 arcsec separation (excludes target name correlations) 30 = Simbad spectral type used |
integer |
| st_target |
Skiff Target |
Target name from Skiff table (if found). When a common name is not known, the convention was to use the authors initials followed by the year of publication all in brackets, followed by a number as assigned in the publication (e.g., [BE74] 185 ). |
