Colors can be directly compared to data in the 2MASS photometric
system; for details of the photometric system and the various error
sources that are considered here, see Sects. 3.1 and 2.1. a Corrected for galactic extinction (see Sect. 2.1). b Possible local instabilities in one SBP at low S/N levels. c Possible contamination by nebular emission over a large portion of the LSB host galaxy. |
