Stimuli were displayed on a 22-in. Philips 202P4 CRT monitor with a refresh rate of 85 Hz. The minimum and maximum luminance of the screen were 0.6 and 112.1 cd/m2, respectively, and the mean luminance was 56.8 cd/m2. Luminance was measured with a CRS Optical photometer (OP200-E; Cambridge Research System Ltd., Rochester, Kent, UK). A digital-to-analog converter (Bits#, Cambridge Research Systems, Cambridge, UK) was used to increase the dynamic contrast range (12-bit luminance resolution). A 12-bit gamma-corrected lookup table (LUT) was applied so that luminance was a linear function of the digital representation of the image. The screen resolution was 1600 × 1200 pixels.
202p4 crt monitor
Manufactured by Philips
The Philips 202P4 CRT monitor is a professional-grade display designed for laboratory and scientific applications. It features a 20-inch diagonal screen with a CRT (Cathode Ray Tube) display technology, providing a stable and reliable image quality. The monitor supports a maximum resolution of 1600 x 1200 pixels and has a refresh rate of up to 85 Hz. It is intended for use in controlled environments where precise color accuracy and image stability are critical requirements.

Stimuli were presented on a 22-in Philips 202P4 CRT monitor with a resolution of 1280 3 1024 pixels at 100 Hz. The viewing distance was set to 70 cm from the observer so that the display subtended 15.88 3 21.18 of visual angle. The stimuli were generated and presented using MATLAB software (Mathworks) and the Psychophysics Toolbox extensions (Brainard, 1997) . Observers' eye movements were monitored and recorded using an Eyelink 1000 infrared eye tracker (SR Research, Kanata, Ontario, Canada). Head position was maintained using a forehead and chin rest, and eye position signals were sampled from the eye tracker at 1000 Hz.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
