Dr. Kato,

	Thank you for your response.  It was very helpful.  I have several more
questions for you.  First, what is GSC magnitude?  What exactly is 'flux
at X microns'?  Also, how big of a telescope would you need to see this?

	Thanks again,
		Anna C. Gheen

Reply to the first question:

GSC3868.224 150751.82 +544510.0 (2000.0) 13.63 1 N
----------- ===================          ----- magnitude
object name these values are coordinates of the object

   This line means

  object name: GSC 3868.224
  coordinates: 15h 07m 51s.82, +54o 45' 10".0  (J2000.0)
  GSC magnitude: 13.63
  object type: N (non-stellar)

    F12=0.25L F25=0.25L F60=0.52  F100=2.09 
    VAR=-1 LRS=-1

  This line indicates the IRAS identification (infrared properties).

  object name: IRAS 15064+5456
  F12 (flux at 12 micron): lower than 0.25 Jy
  F25 (flux at 25 micron): lower than 0.25 Jy
  F60 (flux at 60 micron): 0.52 Jy
  F100 (flux at 100 micron): 2.09 Jy

  Other two IRAS catalogues, SSC and FSC identifications.

150751.5 +544509 (2000.0) N5874

  object name = NGC 5874

150751.6 +544510 (2000.0) CfA_N5874 v=3128km/s Bmag=14.1

  CfA redshift survey.  Recession velocity = 3128 km/s, total B
magnitude
  = 14.1

150752.3 +544511 (2000.0) RC3_NGC5874 PGC54018 .SXT5.. BT=13.12

  RC 3 galaxy information.  ".SXT5.." indicates the galaxy morphological
classification.
