This file is used in Derive-SPD to correct for the effects of electrical crosstalk (see section 8.2.6).

The file contains 12 records, each 52 integers in length. The first 12 numbers in each record contain the crosstalk for band 1, the next 12 for band 2 etc. Record 1 contains the crosstalk between detector 1 in each band and the other detectors in that band, record 2 contains the crosstalk between detector 2 in each band and the other detectors in that band, etc. Only records 1 and 2 contain information for bands 5 and 6 (the FP bands with only 2 detectors in each).

9.5.2 SWS Cal-G 2 RC correction timescales

This file, used in Derive-SPD, contains the time constants for the high pass filter in the amplifier chain (see section 8.2.5). It contains 52 numbers, the timescales per detectors in seconds.

9.5.3 SWS Cal-G 2A Midbit values

This file, used in Derive-SPD, contains the midbit value for each detector (see section 8.2.3). The detector readouts are between 0 and 4095 (bits) corresponding to -10 to 10 Volts. The midbit is the bit value that corresponds to 0 Volts, approximately 2048, and is different for each detector.

9.5.4 SWS Cal-G 2B Shape correction values

This is used in Derive-SPD. After the slope has been corrected for the reset pulse it is not straight. This files contains values to correct it, see section 8.2.4.

Currently this calfile is filled with zeros which results in the OLP chain not correcting for reset pulse shape.

9.5.5 SWS Cal-G 3 Reset cutout lengths

This file, used in Derive-SPD and Auto-Analysis, contains the number of 24Hz readouts to ignore after a reset (short circuit of the capacitor) (see section 8.2.2). It contains 52 numbers, the number of readouts to ignore per detector.

9.5.6 SWS Cal-G 4 Amplifier limits

This file, used in Derive-SPD, contains the SWS amplifier limits, the minimum and maximum allowable voltages from the amplifiers (see section 8.2.2). There are 52 records, each of which contains the minimum and maximum voltages for the three gains (gain 1, 4 and 16), in telemetry units.

9.5.7 SWS Cal-G 5 Switchable gains

This file, used in Derive-SPD, contains the gains used to convert between the slopes generated from the 24Hz information and the voltages on the detectors (see section 8.2.10). There are 52 records, one per detector. Each record contains three numbers, one for each gain.

9.5.8 SWS Cal-G 6 Glitch reject levels

This file, used in Derive-SPD, contains information used to recognise glitches and reject them (see section 8.2.7). It contains 52 records, one per detector. Each record contains four numbers: $\alpha$ ; the number of readouts to ignore before and after a glitch; and the minimum width of a glitch. The last three are in units of 24 Hz samples.

9.5.9 SWS Cal-G 7 Grating detector noise characteristics

9.5.10 SWS Cal-G 8 Grating calibration specifications

9.5.11 SWS Cal-G 9 LVDT-Angle relation

9.5.12 SWS Cal-G 10 Key wavelengths

9.5.13 SWS Cal-G 11 FP calibration spectrum

9.5.14 SWS Cal-G 12 Gap-position relation

This file, used in Derive-SPD, contains information on the gap, current and position relationship of the two FPs (see sections 8.2.13 and 7.5). Each record contains the FP position (a telemetered number) applicable to both FPs, and then for each FP the main current and two correction currents necessary to achieve this position, and then the corresponding gap for those currents, in $\mu m$ .

9.5.15 SWS Cal-G 13 Relative flux

This file, used in Auto-Analysis, contains information used in the flux calibration. There is one row per key wavelength. Each row has the name of the AOT band, the key wavelength, two numbers defining the passband used. Then come conversion numbers for each detector in that band (by default 12, with 10 blank for FP bands) in $\mu V/ sec/ Jy$ , then 12 internal calibration signals (in $\mu V/sec$ ), then 12 relative flux calibrations (in Jy), then errors on the conversion numbers (in $\mu V/ sec/ Jy$ ), errors on the internal calibrations (in $\mu V/sec$ ), errors on the relative flux calibrations (Jy) and finally the grating start and end position.

9.5.16 SWS Cal-G 14 Intensity of internal calibration sources

9.5.17 SWS Cal-G 15 Intensity of calibration sources

9.5.18 SWS Cal-G 16A Aperture offsets

This file, used in Derive-SPD, contains the angles, in degrees, from the optical axis to the entrance or light source used, as seen from the SW and LW collimators (see section 7.5).

9.5.19 SWS Cal-G 16B Element offsets

This file, used in Derive-SPD, contains the angles, in degrees, from the optical axis to the detectors for each of the detectors (see section 7.5).

9.5.20 SWS Cal-G 16C Grating constants

This file, used in Derive-SPD, contains information of the effective gap correction. For each possible FP wavelength there is a gap correction for each of the two FPs. All units are $\mu m$ .

9.5.24 SWS Cal-G 19 AOT 1 resolution factors

Cal-G 19 is used in the processing of all speed AOT 1's. It contains the factors needed to smooth the RSRF's of each AOT band down to the spectral resolution of the AOT 1 being processed and hence match the resolutions.

This was added in OLP V5.0 but the file was described incorrectly in the SWS IDUM V3.0.

These 4 files, Cal-G 21_1, Cal-G 21_2, Cal-G 21_4 and Cal-G 21_8 contain information on the dark current. There is one file per reset interval. Each file contains 52 records, each containing the detector number, the average measured dark current (from ground and PV phase tests). the noise in the dark current and finally the minimum and maximum valid dark currents.
