st_target |
Target Name |
Target name as specified in Skiff's catalog |
Examples: 10 Lac, HD 141556 |
char |
st_string |
Spec Class |
Spectral classification as specified in Skiff's catalog. String is mixed case and matches must be exact. Only spectral types determined from spectra (viz.line and band strengths or ratios) are included, omitting those determined from photometry (e.g. DDO, Vilnius) or inferred from broadband colors or spectral energy distributions. |
B0Vpe |
char |
st_ra |
Target RA |
Right Ascension (J2000) |
Range 0 to 360 deg |
double |
st_dec |
Target Dec |
Declination (J2000) |
Range: -90 to +90 deg |
double |
st_type |
TT |
Encoded spectral type TT specified as an integer (e.g., TT=12 for A stars). See the Spectral Classification Tables. |
Range: 0 and 10 to 56 (see table ?) |
long |
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 ?) |
long |
st_lum |
LL |
Luminosity class specified as an integer from 10 to 35. See the Spectral Classification Tables. |
Example: 0 and 10 to 35 (see table ?) |
long |
st_p1 |
P1 |
First encoded global peculiarity. Also indicates composites stars (p1=1). See the Spectral Classification Tables. |
Range: 0 to 9, 0 = unknown |
long |
st_p2 |
P2 |
Second encoded global peculiarity (must have a different value from P1). See the Spectral Classification Tables. |
Range: 0 to 9, 0 = unknown |
long |
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 |
long |
st_p4 |
P4 |
fourth 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 |
long |
st_rest |
unparsed text |
Part of original spectral clasification ignored or unable to be parsed in the encoding process. |
Mixed-case string |
char |
st_date |
Pub. Year |
Year of paper in which spectral classification was first published (from Skiff's catalog) |
2001 |
long |
st_bibcode |
Bibcode |
Bibcode for latest publication found (from Skiff's catalog) |
|
char |
st_mag |
Magnitude |
Magnitude (from Skiff's catalog) Magnitudes were provided as an indication of brightness, but these data are not necessarily accurate, as they often derive from photographic photometry or rough estimates. |
|
long |
st_cflag |
D 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 |
long |
st_id |
st_id |
A sequential integer used internally as a unique ID. |
