There is strong indication that not only T Tauri stars are associated with discs but also intermediate- and high-mass YSOs. For a part of the target objects we search for emission from the outflows. The energy distribution will be determined for all sources of the sample. OBSERVATION SUMMARY We selected seven typical compact infrared sources from a compilation of very young and luminous YSOs. We will use ISOPHOT-C100 to make 3x5 raster observations on the target sources with AOT P32. The filters C60 and C100 will be applied. In addition, we want to measure all sources with PHOT-P beginning with multi-aperture photometry at 7.7 and 25 microns (AOT P04) and following with multi-filter photometry (AOT P03) at 3.6, 4.85, 7.3, 10, 12.8, 16, 20, 25, and 60 microns. <=== scientific_justification ===> Team top 40% second 30% last 30% PHT: 5045 3599 0 SOT: 5940 0 0 total: 10985 3599 0 <=== autumn_launch_targets ===> 1, "PHT32", 2.0, "N", "S 187 ", 1.32528, 61.60972, 1950, 0.000, 0.000, 1402, 2 2, "PHT04", 2.0, "N", "S 187 ", 1.32528, 61.60972, 1950, 0.000, 0.000, 249, 3 3, "PHT04", 2.0, "N", "S 187 ", 1.32528, 61.60972, 1950, 0.000, 0.000, 179, 4 4, "PHT03", 2.0, "N", "S 187 ", 1.32528, 61.60972, 1950, 0.000, 0.000, 387, 0 5, "PHT32", 1.0, "N", "AFGL 2059 ", 18.03028, -24.44917, 1950, 0.000, 0.000, 1402, 6 6, "PHT04", 1.0, "N", "AFGL 2059 ", 18.03028, -24.44917, 1950, 0.000, 0.000, 249, 7 7, "PHT04", 1.0, "N", "AFGL 2059 ", 18.03028, -24.44917, 1950, 0.000, 0.000, 163, 8 8, "PHT03", 1.0, "N", "AFGL 2059 ", 18.03028, -24.44917, 1950, 0.000, 0.000, 381, 0 9, "PHT32", 1.0, "N", "S 106 ", 20.42583, 37.21389, 1950, 0.000, 0.000, 1402, 10 10, "PHT04", 1.0, "N", "S 106 ", 20.42583, 37.21389, 1950, 0.000, 0.000, 249, 11 11, "PHT04", 1.0, "N", "S 106 ", 20.42583, 37.21389, 1950, 0.000, 0.000, 179, 12 12, "PHT03", 1.0, "N", "S 106 ", 20.42583, 37.21389, 1950, 0.000, 0.000, 435, 0 13, "PHT32", 1.0, "N", "AFGL 2591 ", 20.45972, 40.02055, 1950, 0.000, 0.000, 1402, 14 14, "PHT04", 1.0, "N", "AFGL 2591 ", 20.45972, 40.02055, 1950, 0.000, 0.000, 249, 15 15, "PHT04", 1.0, "N", "AFGL 2591 ", 20.45972, 40.02055, 1950, 0.000, 0.000, 163, 16 16, "PHT03", 1.0, "N", "AFGL 2591 ", 20.45972, 40.02055, 1950, 0.000, 0.000, 383, 0 17, "PHT32", 2.0, "N", "S140-IRS ", 22.29472, 63.06222, 1950, 0.000, 0.000, 1402, 0 18, "PHT32", 1.0, "N", "Cep A ", 22.90556, 61.76528, 1950, 0.000, 0.000, 1402, 19 19, "PHT04", 1.0, "N", "Cep A ", 22.90556, 61.76528, 1950, 0.000, 0.000, 249, 20 20, "PHT04", 1.0, "N", "Cep A ", 22.90556, 61.76528, 1950, 0.000, 0.000, 179, 21 21, "PHT03", 1.0, "N", "Cep A ", 22.90556, 61.76528, 1950, 0.000, 0.000, 381, 0 22, "PHT32", 1.0, "N", "NGC 7538-IRS1 ", 23.19333, 61.19917, 1950, 0.000, 0.000, 1402, 23 23, "PHT04", 1.0, "N", "NGC 7538-IRS1 ", 23.19333, 61.19917, 1950, 0.000, 0.000, 249, 24 24, "PHT04", 1.0, "N", "NGC 7538-IRS1 ", 23.19333, 61.19917, 1950, 0.000, 0.000, 163, 25 25, "PHT03", 1.0, "N", "NGC 7538-IRS1 ", 23.19333, 61.19917, 1950, 0.000, 0.000, 379, 0 <=== spring_launch_targets ===> 1, "PHT32", 1.0, "N", "AFGL 490 ", 3.39389, 58.61000, 1950, 0.000, 0.000, 1402, 2 2, "PHT04", 1.0, "N", "AFGL 490 ", 3.39389, 58.61000, 1950, 0.000, 0.000, 249, 3 3, "PHT04", 1.0, "N", "AFGL 490 ", 3.39389, 58.61000, 1950, 0.000, 0.000, 163, 4 4, "PHT03", 1.0, "N", "AFGL 490 ", 3.39389, 58.61000, 1950, 0.000, 0.000, 383, 0 5, "PHT32", 2.0, "N", "S 255-IRS1 ", 6.16583, 18.00333, 1950, 0.000, 0.000, 1402, 6 6, "PHT04", 2.0, "N", "S 255-IRS1 ", 6.16583, 18.00333, 1950, 0.000, 0.000, 249, 7 7, "PHT04", 2.0, "N", "S 255-IRS1 ", 6.16583, 18.00333, 1950, 0.000, 0.000, 163, 8 8, "PHT03", 2.0, "N", "S 255-IRS1 ", 6.16583, 18.00333, 1950, 0.000, 0.000, 411, 0 9, "PHT32", 1.0, "N", "AFGL 961E ", 6.53306, 4.25222, 1950, 0.000, 0.000, 1402, 10 10, "PHT04", 1.0, "N", "AFGL 961E ", 6.53306, 4.25222, 1950, 0.000, 0.000, 249, 11 11, "PHT04", 1.0, "N", "AFGL 961E ", 6.53306, 4.25222, 1950, 0.000, 0.000, 163, 12 12, "PHT03", 1.0, "N", "AFGL 961E ", 6.53306, 4.25222, 1950, 0.000, 0.000, 385, 0 13, "PHT32", 1.0, "N", "S 106 ", 20.42583, 37.21389, 1950, 0.000, 0.000, 1402, 14 14, "PHT04", 1.0, "N", "S 106 ", 20.42583, 37.21389, 1950, 0.000, 0.000, 249, 15 15, "PHT04", 1.0, "N", "S 106 ", 20.42583, 37.21389, 1950, 0.000, 0.000, 179, 16 16, "PHT03", 1.0, "N", "S 106 ", 20.42583, 37.21389, 1950, 0.000, 0.000, 435, 0 17, "PHT32", 1.0, "N", "AFGL 2591 ", 20.45972, 40.02055, 1950, 0.000, 0.000, 1402, 18 18, "PHT04", 1.0, "N", "AFGL 2591 ", 20.45972, 40.02055, 1950, 0.000, 0.000, 249, 19 19, "PHT04", 1.0, "N", "AFGL 2591 ", 20.45972, 40.02055, 1950, 0.000, 0.000, 163, 20 20, "PHT03", 1.0, "N", "AFGL 2591 ", 20.45972, 40.02055, 1950, 0.000, 0.000, 383, 0 21, "PHT32", 2.0, "N", "S140-IRS ", 22.29472, 63.06222, 1950, 0.000, 0.000, 1402, 0 22, "PHT32", 1.0, "N", "Cep A ", 22.90556, 61.76528, 1950, 0.000, 0.000, 1402, 23 23, "PHT04", 1.0, "N", "Cep A ", 22.90556, 61.76528, 1950, 0.000, 0.000, 249, 24 24, "PHT04", 1.0, "N", "Cep A ", 22.90556, 61.76528, 1950, 0.000, 0.000, 179, 25 25, "PHT03", 1.0, "N", "Cep A ", 22.90556, 61.76528, 1950, 0.000, 0.000, 381, 0
