| Abstract | ||
| The Kottamia Faint Imaging Spectro-Polarimeter (KFISP) was recently designed for installation on the 1.88 m Cassegrain Telescope at the Kottamia Astronomical Observatory (KAO) in Egypt. A retrofit was implemented to address optical issues in the initial design of KFISP. This paper presents a comparison of photometric standard magnitudes for the open star cluster M52 and two published catalogues of standard stars, using KFISP in BV filters. For this comparison, a number of statistical tools were used, such as analysis of variance (ANOVA), statistical hypothesis testing, and correlation coefficients. For BV filters, the correlation coefficients between the published catalogues and KFISP observations are remarkably strong. ANOVA results show no significant differences in standard magnitudes between KFISP and the other sources for both standard stars and the M52 open star cluster, demonstrating that KFISP observations are consistent with the published catalogues. | ||
