NICMOS Phase II

When writing a NICMOS Observing Program, NICMOS observers are assigned a Program Coordinator (PC) as identified in their acceptance letter from the STScI Director. The PC will contact the observer to introduce themselves and help get the Phase II process started.

Additional help can be requested from a Contact Scientist (CS). A Contact Scientist is an Instrument Scientist involved in the calibration and characterization of NICMOS.A CS is assigned to ToO, Moving Target, and some other programs. They are not normally assigned to GO programs. A GO may request that a CS be assigned to their program.

The Phase II Proposal Instructions can be found on the STScI web page. STScI is no longer printing the Phase II Proposal Instructions (P2PI) and do not maintain an inventory of copies. To help the Observer get started, some additional information is provided for: parallel, patterns, and grism observations. For more specific Phase II related information, follow the links to the documents listed below.

Four MIF MULTIACCUM timing sequences (MIF512, MIF1024, MIF2048, and MIF3072) have been replaced by four new SPARS MULTIACCUM timing sequences. The four new timing sequences are SPARS4, SPARS16, SPARS32, and SPARS128. Each timing sequence has two rapid reads at the beginning and end with evenly spaced read outs of 4s, 16s, 32s, and 128s,respectively.

The individual detector read times for the new SPARS sequences are listed in Chapter 12 of the Cycle 14 Phase II Instructions. And, the timing sequences are selectable "Optional Parameters" with APT version 14.2 .

The new SPARS sequences can be most useful for fields with faint sources; i.e., galaxies, nebulae, and faint star clusters.
