Details on Acronym:   [TSW99]
  
[TSW99] (Thompson+Storrie-Lombardi+Weymann+, 1999)
Write:<<[TSW99] NNN.NNNa>>
<<[TSW99] NNNN.NN>>
N: 342+205+35
Object:G  (SIMBAD class: Galaxy)
Note:NICMOS observations of the HDF.
Format NNN.NNN or NNNN.NN:
The first three digits are from 1 to 303 for the detected sources, 501 to 705 for sources with signal-to-noise ratio levels less than 2.5.
The first four digits are among 1018 to 1985 when not in the original KFOCAS catalog (1999AJ....117...17T), but added in the second paper (2001ApJ...546..694T).
The second group of digits after the decimal point indicate the level of splitting by KFOCAS up to 3 levels of daughter objects.
In the second paper, objects format is always with 6 digits, so object 1.000 is designated as 1.00000, object 10.000 as 10.0000 and objects added as NNNN.NN (1092.00 for ex.)
