Ref.735 reported a period of 1.756 HD5601 1 days, which was determined from the photometric data of HIPPARCOS . The HD5601 1 photometric variability of the star is low and the amplitude is comparable to HD5601 1 the accuracy of measurements. Therefore, determination of the period from the HD5601 1 photometric data yields uncertain results.

This period does not coincide with the period HD40535 of pulsations nor with the period of the Blazhko effect. Additional measurements HD40535 of the magnetic field and polarimetric data are necessary to determine the HD40535 period and MPC parameters. Open circles - ref.362. HD41403 The MPC is a simple sine wave but it is highly uncertain, because is not HD41403 adequately covered by B_l estimates. One of the probable magnetic periods HD41403 equals 4750 days; variability of the magnetic field is very slow. Additional HD41403 observations are necessary for the determination of period and MPC parameters. HD41403 Open circles - ref.402 HD43317 1 The MPC is a double sine wave. The period of 0.897673 days is from ref.792. HD43317 1 Measurements in all lines were used. Filled circles - ref.793, open HD43317 1 circles - ref.794. HD43317 2 The MPC is a double sine wave.
