Any source?
the fact that parts of HXMT or a simulator was shipped to JSLC last year before being shipped back.

I'm told that a rocket is in final process of stacking on the pad. type is unknown until later stages arrive.

I found this interesting presentation, delivered by Fangjun Lu in 2013:
The Current Status and Calibration Plan of the Hard X-ray Modulation Telescope Projecthttp://web.mit.edu/iachec/meetings/2013/Presentations/Lu.pdfIt gives this information:
Orbit: 550 km, 43 deg.
Mass: ~3000 kg
Instrument Mass: ~1000 kg
***
This paper in 2004 in
Advances in Space Research https://www.researchgate.net/publication/222235318_HXMT_satellite_for_space_hard_X-ray_observation explains why this orbit was chosen: to stay below (most of) the Van Allen belt and to minimize the effects of the South Atlantic Anomaly.
***
The paper also summarizes the method used for hard X-ray imaging: collimated detector and the Direct Demodulation (DD) imaging technique.
***
Regarding the launch vehicle change from CZ-2D to CZ-4B, I learn from Gunter's Space Page
http://space.skyrocket.de/doc_lau_fam/df-5.htm , that a CZ-2D can launch a 3300 kg payload to LEO, while a CZ-4B can launch a 4200 kg payload to LEO.
Was the launch vehicle changed to provide a greater margin of performance?

AFAIK, CZ-2D is still grounded from last years failure from TSLC so that is the reason for the switch.

China launches space telescope to search for black holes, pulsarshttp://news.xinhuanet.com/english/2017-06/15/c_136367703.htmJIUQUAN, June 15 (Xinhua) -- China launched its first X-ray space telescope to observe black holes, pulsars and gamma-ray bursts, via a Long March-4B rocket from Jiuquan Satellite Launch Center in northwest China's Gobi Desert at 11 a.m. Thursday.
The 2.5-tonne Hard X-ray Modulation Telescope (HXMT), dubbed Insight, was sent into an orbit of 550 kilometers above the earth to help scientists better understand the evolution of black holes, and the strong magnetic fields and the interiors of pulsars.
Through the telescope, scientists will also study how to use pulsars for spacecraft navigation, and search for gamma-ray bursts corresponding to gravitational waves.
The result of the wisdom and efforts of several generations of Chinese scientists, Insight is expected to push forward the development of space astronomy and improve space X-ray detection technology in China.

CAMSAT CAS-4A & 4B Linear Transponder Payloads Launched
Posted on June 15, 2017 by N8HM
CAMSAT has announced the launch of its CAS-4A and CAS-4B linear transponder payloads. These payloads piggyback on the OVS-1A and OVS-1B optical remote sensing satellites, which were launched along with the hard X-ray modulation telescope (HXMT) satellite aboard a CZ-4B rocket from Jiuquan Satellite Launch Center at 03:00 UTC on June 15, 2017. Both satellites are in a 43 degree inclination orbit with an apogee of 524 km.
