The FAST open call for proposal issued by NAOC requires that new proposals should avoid duplication with prioritized major projects. To facilitate planning by astronomical colleagues, the specific coverage (see p2-p3) and mode (p4) are refined below with some additional information. 
1The CRAFTS project team is ready to provide unconditional access to already acquired survey data, and peers are welcome to utilize CRAFTS already acquired data or planned observations in their proposals and science analyses. 
2CRAFTS uses a specific deflection angle drift scan combined with high-frequency noise, which is an effective mode for FAST to realize the coverage of a large sky area with super-Nyquist sampling, and peers are welcome to use it. The project team unconditionally provides the calibration process and related processing software, and is willing to participate in the technical discussion without making any request for scientific cooperation or data.  
3Any observation project outside the range of -14 degrees to +5.5 degrees declination is not within the current 5-year planning of CRAFTS, and there is no question of duplication with this project.  
4For targets within -14 degrees to +5.5 degrees of declination, only one long continuous drift scan is considered a duplicate. For example, science targets that require multiple scans, or braided scans of feature areas, can be considered new observations with no conflict with existing projects. In these cases, the CRAFTS model, data, and processing flow are still welcome.
5) With an update date of 2022-08-01, approximately 18% of the sky coverage has been completed and 151 CRAFTS observations have been made. See "CRAFTS Current Sky Coverage

FAST Open Call for Proposal

Call for FAST Science Observing Proposals link The Five-hundred-meter Aperture Spherical radio Telescope (FAST), a Chinese national science facility, welcomes submission of science proposals for the upcoming observing period scheduled from August 2021 to July 2022. Users of any nationalities or affiliations are invited to submit proposals before the deadline at 24:00 UT on 15th May 2022 through the website http://fast.bao.ac.cn/proposal_submit . Information on the techniques and current performance of the telescope are available at http://fast.bao.ac.cn . The FAST science operation covers both regular science programs and large programs. Please note that this Call only solicits regular science proposals, which usually take observing time no more than 100 hours. It is anticipated that about 1800 hours of observing time will be allocated to regular science programs. All proposals should make it clear that why the FAST is necessary for the requested observations. The FAST started its full operation in January 2020, and is now completing its first science observing period. A list of previously accepted science proposals, including both regular science and large programs, can be found at http://fast.bao.ac.cn . Note that information of future approved proposals, including titles, PI names, abstracts, and scheduling priorities, will also be posted at the website. Science data obtained through a regular science program have a proprietary period of 12 months. Please see the FAST Data Policy posted at http://fast.bao.ac.cn for more details. Proposers should query the FAST archive before planning observations to check if any existing data meet their scientific goals. Should you have any further question about the telescope operation and proposal submission, please contact fast-proposal-support@nao.cas.cn.

Having achieved 'first-light' right before the opening ceremony on September 25, 2016, the Five-hundred-meter Aperture Spherical radio Telescope (FAST) is now kept busy with commissions. Its innovative design requires ~1,000 points to be measured and driven instead of just the two axes of motion, e.g. Azimuth and Elevation for most of the conventional antennae, to realize pointing and tracking. We have devised a survey plan to utilized the full sensitivity of FAST, while minimizing the complexities in operation the system. The 19-beam L band focal plan array will be rotated to specific angles and taking continuous data streams while the surface shape and the focal cabin stay fixed. Such a survey will cover the northern sky in about 220 full days. Our aim is to obtain data for pulsar search, HI (neutral hydrogen) galaxies, HI imaging, and radio transients, simultaneously, through multiple backends. These data sets could be a significant contribution to all related fields in radio astronomy and remain relevant for decades.
