Table 1. List of NSF grating parameters.
"... In PAGE 7: ... Eight VPH gratings were fabricated at KOSI for evaluation. Table1 lists the parameters for all eight gratings. Each grating was measured for its e#0Eciency as a function of wavelength and grating tilt in unpolarized light.... In PAGE 7: ... The e#0Eciency performance of gratings 1, 2, and 3 are presented here. Future papers will address the characteristics of the remaining gratings listed in Table1 . Scattered light and wavefront evaluation will also be given in a future paper that will summarize the performance of all the gratings that were so evaluated.... In PAGE 9: ...3. 300lmm ,1 VPH Grating E#0Eciency Grating 1 in Table1 was fabricated for optimal performance at 1064 nm with a FWHM spectral bandwidth goal of 500 nm. The 72 by 72 mm grating is sandwiched between two 3#7Bmm, uncoated, BK7 substrates with an overall dimension of 77 by 93 mm.... In PAGE 10: ...4. 1200 l mm ,1 VPH Grating E#0Eciency HG#7BT#7B532#7B19, grating 2 in Table1 , was designed to have optimal performance at 532 nm with a FWHM spectral bandwidth goal of 200 nm when operated at 18.61 #0E .... In PAGE 11: ...5. 2400 l mm ,1 VPH Grating E#0Eciency The third grating, HG#7BT#7B532#7B40, in Table1 is a 2400 l mm ,1 grating designed for peak operation at 532 nm with a spectral bandwidth goal of 60 nm. This 72 by 72 mm grating is mounted between two 8 mm, BK7 substrates.... In PAGE 13: ...1#7Bmeter telescope had not been aluminized for nearly #0Cveyears and it is expected that scattering due to the poor coating further suppressed the signal in the core of the stellar image. The e#0Bect of seeing was particularly noticeable on the nightof1 May, 1999, during which the NSF multiplex grating #28grating 6 in Table1 #29 was tested. Although not spectacular, the seeing on that nightwas considerably better than on the previous two nights, measured at 1.... ..."
Table 1 Cryogenic Grating Spectrometer Instrumental Parameters
"... In PAGE 6: ...O J=17-16 (153.4 m) lines were observed at the peak of the [O I] (63.2 m) strip scan. The FWHM beam diameter at each wavelength is given in Table1 . The e ective area of the beam can be obtained by using an e ective diameter which is 1:04 times this FWHM value.... In PAGE 6: ... The e ective area of the beam can be obtained by using an e ective diameter which is 1:04 times this FWHM value. Table1 also gives the detector separation, the spectral resolution, and the detector type for each wavelength. The total bandpass of the detectors was su cient to include both the line and the adjacent continuum using a single grating position.... In PAGE 7: ... The four free parameters are the continuum strength and the line strength, width, and wavelength. All four parameters were varied to t the lines which had high signal-to-noise, but the line widths were xed at the instrumental values in Table1 for the low signal-to-noise spectra obtained for [O I] (145 m) and CO J=17-16 (153 m). The resulting line intensities and the adjacent continua are given in Tables 2 and 3.... ..."

Table 2 The results of a query constructed in the Microsoft Access database, CSDSymmetry, that determines which point groups contain the highest proportion of their molecules in non-centrosymmetric space groups.
"... In PAGE 7: ... The number of molecules, grouped by point group, contained in space groups that do not contain a centre of inversion has been determined and compared with the number of molecules found in each point group for the entire CSDSymmetry database. A user-defined equation was formulated to calculate the percentage of molecules of a particular point group that are found in non-centrosymmetric space groups: the ten point groups with the highest percentage of molecules in non- centrosymmetric space groups are given in Table2 . A criterion was placed on the query that there had to be more than 30 occurrences of the point group in the whole database.... ..."
Table 1. Details of rst order grating spectra analyzed
"... In PAGE 1: ... The data consists of expo- sures at six wavelength settings for each grating obtained around January 14th and May 20th (in SMS 92103 and 92139 respectively). Table1 lists the data les with brief details. Although equivalent data for Echelle-B was not available, analysis of multi- ple exposures at the same wavelength setting (taken with the spectrum y-balance,... In PAGE 2: ..., 1991). The data taken in January 1992 (see Table1 ) had been wavelength calibrated by the PODPS pipeline using the erroneous dispersion constants reference table (ba412199z.cz6).... In PAGE 7: ...Table1 . Continued.... ..."
