12:18:35 Selecting filter B from previous ACP run at 20240224@121615 UTC
12:18:35 Imager readout modes:
12:18:35   0 is Fast
12:18:35   1 is Normal

12:18:35 Guider plate scale is 0.2 arcsec/pix. Guided dither with main imager pixels
12:18:35 Max unguided exposure 60 sec.
12:18:35 Guider is set to multi-star mode
12:18:35 (assuring that FocusMax is running now...)
12:18:35 Calculated unbinned plate scales (arcsec/pix): H = 0.23 V = 0.23
