Spectral Characterization of Bright Infrared Sources comma Part 1 of 2

scientific abstract the primary objective of this proposal is to construct an iso database for spectral classification of the brightest representive sources characterized by the iras low resolution spectrometer (lrs) classification, the nasa ames ai classification of the lrs and a sampling based on mk spectral type or iras color. in order to obtain the large and statistically significant database required to develop a comprehensive spectral classification scheme, we propose to complement and add to spectral measurements proposed by other central program and open time observers. we also need to include the spectral measurements made for calibration and benchmarking purposes. consequently, except for the data for which the sws and sot consortia have the rights, we will have to wait until the data taken by others get into the public domain to proceed with the classification effort. the majority of our dedicated time will be devoted to observations with the sws in the rapid scan mode, sws01, and with phot in the phts mode. we propose to concentrate this effort towards sources which are poorly segregated in the present classification schemes and are not likely to be observed for other reasons. examples of such objects are mk a through s stars which were too faint for the lrs, and sources whose selection was based on their infrared colors and the emission line objects in the lrs classes 7, 8 and 9. observation summary to fill our initial classification matrix, we required a minimum of two stars in each lrs, ai, mk or color catagory or 10% of the number of sources in a highly populated class with lrs spectra. these objects formed an initial list of 1316 sources, resulting in over 700 entries in each list for the two iso launch dates. the mission database will be surveyed to identify which sources specified by other observers can be used for the classification objective of this proposal (using sws01, tru [truncated!, Please see actual data for full text]
