ABSTRACTThis paper is a continuation of LPL Comm. 123 covering the interval \\ 10657-12857 A. The arrangement is the same
as in Report I.
In the interest of prompt publication, we are herereproducing Charts 7-15 of the Infrared SolarSpectrum Atlas. LPL Comm. No. 123 covers theregion AA 8487-9725 A, much of it recorded twice.The original observing plan called for a continuousrecord to the longer wavelengths, but the regionAA 9758-10657 A, which contains no strong telluriclines and which had been very well recorded in theLiege Atlas, had to be omitted when a second run ofthe important A 9000 A region became necessarybecause of heliostat troubles. Chart 7 begins withtwo short sections that continue the two parallelrecords of Chart 6. Thereupon, an unbroken recordwith the 1200-line grating is available from A 10657-A 12857 A, recorded in two parts that overlap fromAA 12244-12314 A. A small second gap (about 300A) follows, whereupon the 1200-line record continues to about 14400 A, through the heavy part ofthe 1.4 p. water-vapor band. (This gap, again, wasnot planned, but had to be accepted as the flightschedule evolved; both gaps were covered, however,with lower resolution.)
In addition, the 600-line-per-mm grating recordsstart at 12188 A and continue without break toA 29000 A, continued in turn with 300-line/mmgrating coverage to about 33000 A (cf. LPL Comm.No. 125).
The present report covers the interval AA 10657-12857 A with the 1200-line/mm grating. In thisregion precise wavelength calibrations did not present major problems. Up to A 12016 the Liege Atlascould be used, supplemented by laboratory spectraof the 11350 A water-vapor band and of the 12055and 12206 A CO- bands, roughly matching the intensities in our solar spectra. These laboratory spectra were kindly obtained by Dr. Uwe Fink and Mr.A. Thomson. Beyond the A 12016 A limit, the Tableof Solar Spectrum Wavelengths, 11984 A-25578 Aby O. C. Mohler (1955) was used almost exclusively.
Both sources proved invaluable also in the verification of some of the weaker lines shown on ourspectra. Normally, duplicate records would haveserved that purpose, and some regions were indeedrecorded twice. In general, the flight schedules did
