LAMP_LLL.nnn - Lamp File
The Lamp file is created at the factory by an initial Quick Scan.
Subsequent QS scans append data to LAMP_LLL.nnn, using the first line as a reference.

LAMPLLL.IRX - Lamp Irradiance File
Lamp Irradiance files, generated at the factory, tabulate the UV irradiance of the UV test lamps.
First row - lamp identification number
Second row - distance between lamp filament and PTFE diffuser
Now the file splits into 2 columns:
First column - wavelength in Angstroms from 2865A to 3630A in 0.5nm Increments.
Second column - irradiance in milli watts per square metre.
PUX, PUF, PUV, PUA: Processed UV files
First row - decimal hours from 00:00 (GMT) Header for each scan includes date, starting time
(hour), ending time (hour), zenith angle, latitude, longitude, location name, instrument # and
measurement type, Row 2 column 1 - GMT time in minutes, column 2 - Wavelength (Angstroms),
column 3 - irradiance (W/m
PXL: Processed lamp files
First row - Lamp Number
Row 2 - distance in centimeters
