About
Data
the Stellar Classification Dataset - SDSS17data was obtained from kaggle
the dataset has the following attributes
| column | description | |
|---|---|---|
| 1 | obj_ID | Object Identifier, the unique value that identifies the object in the image catalog used by the CAS |
| 2 | alpha | Right Ascension angle (at J2000 epoch) |
| 3 | delta | Declination angle (at J2000 epoch) |
| 4 | u | Ultraviolet filter in the photometric system |
| 5 | g | Green filter in the photometric system |
| 6 | r | Red filter in the photometric system |
| 7 | i | Near Infrared filter in the photometric system |
| 8 | z | Infrared filter in the photometric system |
| 9 | run_ID | Run Number used to identify the specific scan |
| 10 | rereun_ID | Rerun Number to specify how the image was processed |
| 11 | cam_col | Camera column to identify the scanline within the run |
| 12 | field_ID | Field number to identify each field |
| 13 | spec_obj_ID | Unique ID used for optical spectroscopic objects (this means that 2 different observations with the same spec_obj_ID must share the output class) |
| 14 | class | object class (galaxy, star or quasar object) |
| 15 | redshift | redshift value based on the increase in wavelength |
| 16 | plate | plate ID, identifies each plate in SDSS |
