Time span: 1973-05-29 to 1974-02-08
These data comprise a raster tab and a line tab. The tabs are in four parts: lines 1-30, data samples 1-60; lines 1-30, data samples 61-120; lines 31-60, data samples 1-60; and lines 31-60, data samples 61-120. The heading information for the raster indicates the following: GMT is the day and time of start of the raster; DET-1 is the detector identifier; FSSUD is the ATM fine sun sensor up/down pointing coordinate in arc seconds at the time of start of the raster; GAMRR is the ATM roll coordinate in arc minutes at the time of start of the raster; CYCLE is the number of day/night cycles since the last launch; REF SEL OPT is the grating reference selected at the time of start of the raster; OPT is the optical reference bit indicator (on or off); MECH is the mechanical reference bit indicator; SAMPLE NO. is the sample number; MODE is the mode selected at the start of the raster; FSSLR is the ATM fine sun sensor left/right coordinate in arc seconds at the time of start of the raster; GRT POS is the number of steps where the grating was moved from the selected reference at the time of start of the raster; N is the number of good data samples in the raster; IBAR is the average of the good data samples in the raster; and ISQR is the average of the squares of the good data samples in the raster. The line tab heading information has the same meaning as the raster tab, except for the following: MECH is the mechanical reference bit indicator in turns of the grating being at or near the mechanical reference; GRT FOS is the number of steps where the grating is from the reference selected. More detailed descriptions of these data can be found in the data handbook for the Harvard EUV Spectrometer on ATM.
