However, very few calibrator objects exist with well established ages and metallicities. A very surprising result from the UKIDSS sample (supported by 2MASS and SLOAN) is that the substellar mass function in the local field appears to decline to lower masses, in marked contrast to the rising initial mass function (IMF) observed in young clusters. Given that such a difference between the present day IMF and the Galactic time-averaged IMF is unlikely, it is very possible that the apparently falling IMF is an artifact of serious errors in either T model atmospheres or the evolutionary isochrones. We propose WFC3 spectroscopy of 4 faint T dwarf calibrators with well established ages and metallicities in the Pleiades and Sigma Ori clusters, and 2 faint field T dwarfs from UKIDSS for comparison. These spectra will constitute vital calibration data for T dwarf atmospheres with a wide range of surface gravities, which will be used to test and improve the model atmospheres. They will also aid preparation for future spectroscopy of the much larger numbers of field T dwarfs to soon be found by VISTA and WISE. These new surveys will permit a more precise measurement of the mass function and detection of even cooler objects. ------------------------------------------------------------------------------------ Observations Description ------------------------ This project takes slitless WFC3 spectroscopy of 6 brown dwarfs with the G141 grism. One brown dwarf is observed in each of the 6 orbits, in a single visit.

The ORIENT ranges are carefully selected to prevent overlap of spectra of stars and galaxies in the field. We want the spectrum to be dispersed towards either Position Angle=263.5 to 269.4 on the sky or PA=273.5 to 282.3 degrees. Calculation is ORIENT=PA+225-0.5+360, where 225 is the WFC3 IR +X instrument orientation and the -0.5 degrees allows for the slight tilt of the spectra with respect to the X-axis. The scheduling window is narrow (about 3 days) so if this is too tight I would suggest reducing the exposure time slightly (e.g. to SAMP=12 per sub-exposure) so that the visit is easier to schedule. There is a fairly bright star located 24 arcsec west of the target but we believe that the 1st order WFC3 spectra will only be 21 arcsec long so there should be no overlap. The zero order image of the bright star should also not overlap.
