Description:
Space-based photometry of sources in our L1641N catalogue, with
Spitzer (3.6, 4.5, 5.8, and 8.0 microns) and ISO satellite (6.7 and
14.3 microns), and ground-based photometry with 2.56m Nordic Optical
Telescope (NOT) in JHks.
Optical spectra (5780-8340Å) of Young Stellar Object (YSO)
candidates in our L1641N source catalogue.
The spectra were taken with the 2.56m Nordic Optical Telescope (NOT)
Dec 02-04 2003 and Jan 08-10 2005 (added from both epochs).
Each spectrum is contained in a 2052x2 FITS file. The first row in
each file is the wavelength [Å]. The second row in each file is the
flux [erg/s/cm2/Å]
