Next: RA/Dec & Dec/RA maps Up: OBSERVING PROCEDURES Previous: ON/OFF (Position Switching) . ... Number of Strips: This is the total number of strips to be covered for the map. The map size (in declination), is then (Number of strips - 1) X (Dec step) + (Beam size). If you wish to do a complete map, you must have (Number of strips) = 2 X INT[(Dec Offset)/(Dec Step)+0.5] +1 . Time per strip: This is the length of ``drift time" for each strip, and it sets the map size in the RA direction. ...

... NICMOS has four detector readout modes that may be used to take data. ... The use of SLOW mode imposes a 3 second readout overhead which increases the minimum possible integration time (to slightly more than 3 seconds). When multiple readouts are obtained in ACCUM mode, the readout overhead becomes rather large (e.g., 30 seconds at the beginning and end of an exposure for NREAD=10 making 60 seconds the minimum exposure time). At this time we advise observers to use the FAST readout mode. ...

The NICMOS team has devised a comprehensive program of observations of the Galactic Center. ... Data in hand give a first look at variability and a detailed look at the search for the tip of the main sequence will be discussed where NICMOS has demonstrated adequate sensitivity and photometric precision to identify likely O8-B1 stars at the Galactic Center. ...

... 739C As one part of a program to detect complete samples of active extragalactic objects, the 3.36x10^-3 sr field centered on alpha=12h04min, delta=+11deg30' (1950.0) was mapped with the Very Large Array at 1411MHz. Sixty-seven maps cover this field so that no point is more than 15arcmin from the nearest map center. ... The rms map noise is 0.030 + 0.001 mJy, and the resulting source list is complete to a map peak flux density S_p = 0.2 mJy within 25 arcmin of the field center. ...

... They are the offset in arcseconds for the x and y inst plane offset, the exposure time in seconds, and the number of exposures at each position. ... A point about offsets should be made here. The dither program uses absolute instrument plane offsets, so you should use object plane offsets to center up on the chip so that the script starts from where you centered up. INST and OBJ offsets are independent so an object offset will not be zeroed out by and inst plane offset, just added to it. ...
