Limiting magnitudes

The detection is made on hypersensitized IN plates covering XX 6900 - 8800 A, where strong CN bands exist in carbon stars spectra. The limiting magnitude of our detection is around 1=13 mag, and about 1 mag fainter than that of the catalog compiled by Stephenson (1973).

The hormetic dose response model indicates that the maximum stimulatory response is modest, being best described as a ceiling effect with the maximum response occurring typically between 30 and 60% greater than control responses. The clinical implications of increases of this limited magnitude must be appreciated in order to determine the clinical effectiveness of pharmaceutical agents. 

Because of the limited magnitude of surface tension gradients and absence of electric double-layer effects, the stabilization of foams in nonpolar liquids requires other ways of retarding the thinning of foam lamellae. These include the high liquid-phase viscosity that has been discussed earlier and increased surface viscosity because of presence of highly viscous or even rigid liquid-crystal films.

A liquid junction potential arises at the interface because in the case that r+ r, the different rates of diffusion of the two ions from high to low concentration generates a charge separation at the interface and hence a potential difference known as a liquid junction potential, ljp- According to the classical theory of liquid junction potentials [P. Henderson, Z. PhysiL Chem. 59 (1907) 118], for a salt and X , this has a limiting magnitude of... 

The limiting magnitude p =p, allows to obtain the greatest value E 3A GPa for GNC aggregates, that is the real value of this parameter [ 1 ]. 

Our NIR mosaics each consist of 81 images taken at 1.24"/pbcel with IR-CAM (58x62 SBRC InSb array) on XJKIRT. The 5point-sources in a 5" software aperture. Several techniques w used to estimate the K completeness limit of the survey we adopt a conservative value of K=16. Photometric accuracy, estimated from repeated observations, is assessed to be 5% at the bright end of the survey (E=10-12) and 20% at the fednt end (K<16). 

Abstract. We have completed observations for a new wide-field infrared survey. The survey covers a total area of 0.8 square degrees to a Sa limiting magnitude of 17.5 at K (2.1 /tm) and 18.5 at H (1.6 ftm). We present prdiminary results from this survey, including gidaxy colours and luminosities. 

We obtained the Galactic center survey with a special purpose infrared camera, which was mounted on the University Hawaii s 61 cm telescope atop Mauna Kea, Hawaii in June 1991. The survey system consists of 25 cm, F/3.S Newtonian telescope and PtSi 512 x 512 infrared camera. The camera uses a Mitsubishi IR CSD, sensitive from 1 to 5 micron. The plate scale is 6.1 X 9.4 arcsec per pixel, giving a field of 40.2 X 52.3 aremin. The filters used were H and K ( central wavdength 1.65 and 2.15 micron respectively). Total field covered in this survey is approximately 3.2 deg in E W X 3.6 deg in N-S directions. The limiting magnitudes of our survey were 12.0 mag at K band and 13.0 mag at H band respectively, however the sensitivities of the concentrated regions are declined by the confusion of stars. 

Abstract. We have obtained deep K-band images of 2 sq. aranin of sky to count galaxies down to a limiting magnitude of 21.5. At the foint end the counts are marginally fairer than those determined by the Hawaii Deep Surrey, but the two results are consistent within the error bars. We also present results from a larger area surrey to K=20.
