Aim for 3-5 spectra, each with between 5,000 and 30,000 counts per pixel. -------------------------------------------------------------------- Remarks: : Very dim companion to very bright star. Target is dimmer star to the East. M: moon within 10 deg. Skip if you do not see the star in the acquisition TV. C: cataclysmic variable: may be fainter than on finding chart. CE: EF Eri is the easternmost star of the pair, and may be 3 mag fainter than the start to its west. G: galaxy. Center on nucleus. N: fading nova o: check finding chart. 40 Eri B is the SE component of a triple system. PP: if not done at the start of the night. Be sure to get one set of bias frames either at the start of end of the night. PM: may have appreciable proper motion. ST: Photometric standard. Please observe only if you could not observe the primary standard Feige 110. X: Insert a wavelength calibration lamp exposure after the 6th observation. -------------------------------------------------------------------- General Notes: Astronomical ephemerides are from SKYCAL,by John Thorstensen Pri: Target priority. 1 = observe object if possible 2 = extra targets; observe only if no Priority 1 target is available 3 = backup/filler targets; low priority Cmp: 1 means take comparison spectrum only before target exposures; 2 means before and after .............................................................................. Notes about finding charts: Charts are at www.astro.yale.edu/buxton/smarts/find_charts/blazars/blazars.html RA & Dec: all coordinates are accurate to 1"; charts can be generated by operator as necessary using LEDAS or DSS. ..............................................................................
